a query that includes one or more terms; and

identification data for identifying native applications installed on the user device, each of the native applications being applications that operate independent of a browser application on the user device;

receiving, by the search system, data identifying web resources responsive to the query, each of the web resources being a resource that is configured to be displayed in a web browser and including content that is displayed as part of the resource in the web browser, and wherein each resource is determined to be responsive to the query based on the content that is displayed as part of the resource in the web browser;

determining, by the search system and from the identification data, a native application installed on the user device;

determining, by the search system, that a first web resource of the web resources responsive to the query includes synchronized content stored at a data store that is accessible from the data store for display by the native application installed on the user device, wherein the synchronized content for the first web resource is the same content that is displayed in the native application, and in response to this determination generating a native application search result that includes native application request data that causes the native application installed on the user device to request the synchronized content; and

providing, by the search system, the native application search result to the user device.

8. The non-transitory computer readable storage medium of claim 7 , wherein:

the identification data for identifying native applications installed on the user device comprises native application identifiers that each respectively identify an installed native application; and

determining that a first web resource of the web resources responsive to the query includes synchronized content stored at a data store that is accessible from the data store for display by the native application installed on the user device comprises accessing data that specifies that a provider of the first web resource provides the synchronized content accessible by the native application.

9. The non-transitory computer readable storage medium of claim 8 , wherein generating a native application search result that includes native application request data comprises generating a native application search result that includes native application request data in the form of a uniform resource locator of the first web resource.

10. The non-transitory computer readable storage medium of claim 7 , wherein:

the identification data for identifying native applications installed on the user device comprises a user device identifier that uniquely identifies the user device; and

determining, from the identification data, a native application installed on the user device comprises accessing, based on the device identifier, account data for the device identifier, the account data being data that specifies native applications installed on the device.

11. The non-transitory computer readable storage medium of claim 10 , wherein determining that a first web resource of the web resources responsive to the query includes synchronized content stored at a data store that is accessible from the data store for display by the native application installed on the user device comprises accessing data that specifies that a provider of the first web resource provides the synchronized content accessible by the native application.

12. The non-transitory computer readable storage medium of claim 7 , wherein determining that a first web resource of the web resources responsive to the query includes synchronized content stored at a data store that is accessible from the data store for display by the native application installed on the user device comprises accessing data that specifies that a provider of the first web resource provides the synchronized content accessible by the native application.

13. A system, comprising:
