Use the content page to organize, access, browse, search, and work with content on the website. The content page is organized by tabs that allow you to browse and work with your own content (My Content), items you've marked as favorites (My Favorites), content shared with you through groups (My Groups), content from your organization (My Organization), and content from ArcGIS Living Atlas of the World (Living Atlas). Each tab allows you to browse and search for content in a focused way. The tabs you see, as well as some of the information and options on the tabs, depend on your account type (organizational or public), whether or not you are signed in, and your privileges.
Another way to find and work with content is using the website search at the top of the site. Use the website search to perform a broader search for items in your organization, and, if your organization is configured to allow searching outside the organization, to find items shared by other organizations.
Browse content
Click Content at the top of the website to browse items using the My Content, My Favorites, My Groups, My Organization, and Living Atlas tabs.
Note:
You must have privileges to create content or own items to see the My Content tab.
You only see the Living Atlas tab if your portal administrator has configured the portal to access Living Atlas content from ArcGIS Online.
When browsing content using the content page tabs, you can do any of the following to help you explore and find items:
- Display items in different ways using the view menu.
- Sort items using the available sort options (and reverse the sort order as needed).
Limit the display to items that interest you using the filters on the left. For example, you can filter by item type, date modified, date created, tags, and how the item was shared. The Item Type filter has additional filters to further refine the results.
To find items that have been marked as authoritative or deprecated in your organization, use the Status filter (available on the My Content and My Organization tabs only).
If your portal administrator configured categories, you can also use the Categories filter on the My Content and My Organization tabs to find items. Even if your administrator did not configure categories, you can also filter Living Atlas content using the Categories filter on the Living Atlas tab. For groups that have group categories configured, group members can use these categories to filter group content from the My Groups tab.
Tip:
When searching for apps, you can choose to narrow your search to registered apps only by clicking the Registered Apps Only button under the Apps filter.
Tip:
Active filters are shown at the top of the results page. Click the x beside the filter to clear it. Clear all active filters at once by clicking Clear filters.
- Explore content shared with you through a specific group by selecting the group on the left of the My Groups tab.
Tip:
You can also view items shared with a specific group using the Content tab of the group page.
Search content
To search for specific items, you can enter search keywords into the focused search box on any of the tabs on the content page. Only content relevant to that tab will be displayed. For example, you can search only your favorite items using the focused search box on the My Favorites tab. To narrow down your search results, use the filters on the left. Use the view option buttons to change the way the results are displayed, and sort the items as needed.
If you prefer to search the entire website instead of searching using the tabs of the content page, use the search box at the top of the site to find maps, layers, apps, scenes, tools, files, and groups. Enter keywords in the search box and choose the type of items you're looking for from the search drop-down menu, for example, Search for Apps. A list of relevant results appears. If you don't see the result you want, do any of the following to narrow or broaden your search results:
To further refine your search results, use the filters on the left. For example, you can filter by item type, date modified, date created, tags, and how the item was shared. The Item Type filter has additional filters to further refine the results.
To find items that have been marked as authoritative or deprecated in your organization, use the Status filter (available on the My Content and My Organization tabs only).
If your portal administrator configured categories, you can also use the Categories filter on the My Content and My Organization tabs to find items. Even if your administrator did not configure categories, you can also filter Living Atlas content using the Categories filter on the Living Atlas tab. For groups that have group categories configured, group members can use these categories to filter group content from the My Groups tab.
Tip:
When searching for apps, you can choose to narrow your search to registered apps only by clicking the Registered Apps Only button under the Apps filter.
Tip:
Active filters are shown at the top of the results page. Click the x beside the filter to clear it. Clear all active filters at once by clicking Clear filters.
- Sort search results using the available sort options (and reverse the sort order as needed).
Continue to refine your keywords and search again as needed to find the items you want. For example, if you want to find a street map, you could enter street and choose Search for Maps. You would see a list of all the maps related to streets. If the list is too long, you can filter the results for a category of maps—web maps or map files. You could also search again for streets AND europe and you would then see only street maps for Europe. You can also try an advanced keyword search to get the results you want.
Work with content
When you discover items by browsing and searching the content page and tabs or using the website search at the top of the site, you can view and access information about the items and work with them in various ways. For example, you can see an item's thumbnail, read a short summary about the item or open its item page to see more details, mark an item as a favorite, quickly see who owns the item and how many times it's been viewed, and open the item.
Do any of the following to work with items from the content page:
- Click a thumbnail image to open the item in the most appropriate app. For example, when you click a map thumbnail, it opens in Map Viewer; when you click a web app thumbnail, its website opens.
- Click the More Options button
to select where the item opens. For example, you could choose to open a map in Map Viewer. - To open the item page and see details about an item, click the item title or click the More Options button and click View item details.
- Click the owner name to learn about the author of the item. The profile includes links to the user's public items and groups.
- If you have privileges to create content, click Add Item on the My Content tab to add items from your computer, the web, or an application.
- If you have privileges to create content, click Create on the My Content tab to create new maps, scenes, hosted web layers, apps, and so on.
- If your portal administrator configured categories for the portal, you can categorize items you own or administer on the My Content tab by selecting one or more of your items and clicking Categorize.
- To delete an item, select the item you want to delete, click Delete, and confirm that you want to delete the item.
- To assign an item to a different owner, click the My Content tab, select the item, click Change Owner, select a new owner and folder, and click Change Owner. To do this, you must have privileges to reassign ownership of content.
- To move an item you own to a different folder, click the My Content tab, select the item, click Move, browse for a folder or create a new one, and click Move.
- To filter content by folder name on the My Content tab, type the name of the folder in the search box above your folders. Click the x to clear the filter.
- To share an item, select the item and click Share. Your privileges determine whether you are allowed to share the item and with whom you are allowed to share it.
Note:
To select an item in table view, check the box beside the item. To select an item in list view or grid view, hover over the thumbnail and click the circle in the upper left corner to add a check mark.

Advanced search
When searching for items using the website search or the focused search on any of the content page tabs, you can perform advanced keyword searches to narrow your results. Advanced keyword search is also available when you search for layers to add in Map Viewer and Scene Viewer. You can use any of the following in your advanced search: fields, range searches, boosting, Boolean operators, and grouping. These are described in the following sections.
Fields
When performing a search for content or groups on the website or in Map Viewer or Scene Viewer, you can either specify a field or use the default fields. For items, the default fields are title, tags, snippet, description, type, and typekeywords. For groups, the default fields are id, title, description, snippet, tags, and owner. The best match is always returned. See the tables below for descriptions of these fields.
You can search a specific field by typing the field name followed by a colon and the term you are looking for (for a term with multiple words, use double quotation marks, such as "washoe county"). If you do not use a field indicator, the default fields are searched. For example, if you want to add a layer to your map and know the name of the owner, you can enter owner: followed by the owner's user name in the search to narrow a potentially long list of results.
Item fields
You can refine your item searches using specific fields in your search string. These fields include the following:
| Field | Details |
|---|---|
id | ID of the item; for example, id:4e770315ad9049e7950b552aa1e40869 returns the item for that ID. |
owner | Owner of the item; for example, owner:esri returns all content published by Esri. Field and value are case sensitive. |
created | The date, expressed in UNIX time, that items were created; for example, created: [0000001249084800000 TO 0000001249548000000] returns all items published between August 1, 2009, 12:00 a.m., and August 6, 2009, 8:40 a.m. |
title | Item title; for example, title:"Southern California" returns items with Southern California in the title. |
type | Type returns the type of item and is a predefined field. For example, type:KML returns items with KML as the type and type:"Geocoding Service" returns items with Geocoding Service as the type. Use quotation marks for more precise results, especially for types that include a space. |
description | Item description; for example, description:California finds all items with the term California in the description. |
tags | The tag field; for example, tags:"San Francisco" returns items tagged with the term San Francisco. |
snippet | Summary; for example, snippet:"natural resources" returns items with natural resources in the summary. |
spatialreference | The spatial reference; for example, spatialreference:102100 returns items in the Web Mercator auxiliary sphere projection. |
accessinformation | Access information, for example, accessinformation:esri returns items with esri as the source credit. |
access | The access field; for example, access:public returns public items. This field is predefined, and the options are public, private, or shared. You will only see private or shared items that you have access to. |
group | The ID of the group; for example, group:1652a410f59c4d8f98fb87b25e0a2669 returns items within the given group. |
numratings | Number of ratings; for example, numratings:6 returns items with six ratings. |
numcomments | Number of comments; for example, numcomments:[1 TO 3] returns items that have one to three comments. |

orgid |
The ID of the organization, for example, orgid:5uh3wwYLNzBuU0Ef returns items within the given organization. |
modified | The date, expressed in UNIX time, that items were last modified; for example, modified:[0000001249084800000 TO 0000001249548000000] returns all items modified between August 1, 2009, 12:00 a.m., and August 6, 2009, 8:40 a.m. |
categories | Organization content categories; for example, categories: "Historical Maps" returns items that are categorized in the portal as historical maps. |
Group fields
You can filter your searches on groups using specific fields in your search string. Only public groups or groups that you have access to will be searched. These fields include the following:
| Group field | Details |
|---|---|
id | Group ID; for example, id:1db70a32f5f84ea9a88f5f460f22557b returns the group for that ID. |
title | Group title; for example, title:redlands returns groups with Redlands in the title. |

access | The access level of the group. Values are private and public. Private is the default; for example, access:private returns private groups. |
isinvitationonly | The isinvitationonly field returns groups that require an invitation to join. For example, isinvitationonly:false returns groups that do not require an invitation to join. This field is predefined with the options true or false. |
orgid | The ID of the organization, for example, orgid:5uh3wwYLNzBuU0Ef returns groups within the given organization. |
Range searches
Range searches allow you to match on-field values between the lower and upper bounds. Range queries can be inclusive or exclusive of the upper and lower bounds. Inclusive range queries are denoted by square brackets. Exclusive range queries are denoted by curly brackets.
For example, to find all items created between December 1, 2009, and December 9, 2009, use created:[0000001259692864000 TO 0000001260384065000].
The created field contains the date and time an item is created in UNIX time. UNIX time, also used for the modified field, is defined as the number of seconds that have elapsed since midnight January 1, 1970. The website stores time in milliseconds, so you need to add three zeros to the end of the UNIX time. Additionally, you need to add six zeros to the front of the number. This is because the number is stored as a string in the database.
Range searches are not restricted to date fields. You can also use range queries with nondate fields, for example, owner:[arcgis_explorer TO esri]. This will find all items from the owners between arcgis_explorer and esri, including arcgis_explorer and esri.
Boost a term
Boosting allows you to control the relevance of an item by boosting its term. To boost a term, use the caret symbol (^) with a boost factor (a number) at the end of the term you are searching. The higher the boost factor, the more relevant the term will be. For example, if you are searching for recent fires and want fires to be more relevant, create the expression recent fires^5.
Boolean operators
Boolean operators allow terms to be combined through logic operators. The website supports AND, plus sign (+), OR, NOT, and minus sign (-) as Boolean operators. Boolean operators must be uppercase.
| Boolean operator | Details |
|---|---|
AND | The AND operator is the default conjunction. This means that if there is no Boolean operator between two terms, the AND operator is used. The AND operator performs matching where both terms exist in either the given field or the default fields. This is equivalent to an intersection using sets. |
OR | The OR operator links two terms and finds a match if either of the terms exists. This is equivalent to a union using sets. To search for an item that contains either the term recent fires or just fires, use the query "recent fires" OR fires. |
+ | The plus sign, or the required operator, requires that the term after the symbol exist somewhere in the given field or the default fields. To search for items that must contain fires and may contain recent, use the query recent +fires. |
NOT | The NOT operator excludes items that contain the term after NOT. This is equivalent to a difference using sets. To search for documents that contain California but not imagery, use the query California NOT Imagery. The NOT operator cannot be used with a single term. |
- | The minus sign, or the prohibit operator, excludes items that contain the term after the symbol. To search for documents that contain California but not imagery, use the query California -Imagery. |
Grouping
You can create subqueries using parentheses to group clauses. This can be very useful if you want to control the Boolean logic for a query.
To search for either California or recent and fires, create the expression (California OR recent) AND fires.
You can group multiple clauses to a single field using parentheses.
To search for a title that contains both the phrase population change and the word recent, use the query title:(+"population change" +recent).
Browse and search tips
- When doing a field search, use a colon (:) after the field name, for example, owner:esri.
- Use double quotation marks to surround terms with multiple words; for example, "map services" returns items with the term map services in a field, whereas map services returns items with either maps or services in a field.
- You can create a search string by linking fields together in your search string with the AND operator, for example, owner:esri AND tags:streets.
- Use uppercase for search operators: AND, OR, and so forth.
- Narrow your search results using available filters and sort them as needed.
- In addition to searching for content through keywords, you can also use the gallery to browse featured items.
- If you want to search for layers with a specific extent to use in a map, use Map Viewer. Open a new or existing map, set the extent, click the Add button, and click Search for Layers.
- Only English terms are supported.
