Abstract

A system searches a first search index based on a search query to obtain first search results and searches a second search index based on the search query to obtain second search results. The system further ranks the first search results using a first ranking algorithm and one or more first ranking parameters to produce ranked first search results, and ranks the second search results using a second ranking algorithm and one or more second ranking parameters to produce second search results, where the one or more first ranking parameters are different than the one or more second ranking parameters and where the one or more second ranking parameters include at least one of previous user feedback associated with custom content that corresponds to the second search index, annotations of the custom content provided by a user, or usage patterns associated with users previously accessing and searching the custom content. The system also provides the ranked first and second search results to a user.

Claims

1. A computer-implemented method comprising:

receiving a search query requesting a search of a collection of custom content resources, wherein resources in the collection of custom content resources are resources exposed to a search engine by a user;

obtaining a custom content search result that the search engine has identified in response to the search query using a custom search index generated from the collection of custom content resources;

obtaining an indication of relative importance for a custom content resource identified by the custom content search result, the indication of relative importance being an indication of the importance of the custom content resource relative to other resources in the collection of resources and being assigned by the user that exposed the custom content resource to the search engine;

determining a score for the custom content search result based on the indication of relative importance for the custom content resource; and

ranking the custom content search result with one or more other custom content search results that were identified by the search engine in response to the received query, using the determined score.

2. The method of claim 1, further comprising receiving, by user input from the user, the indication of relative importance for the custom content resource, including receiving a user selection of one of at least two different indications of relative importance for the custom content resource.

3. The method of claim 1, wherein the indication of relative importance is an annotation to the custom content resource assigned by the user that exposed the custom content resource to the search engine.

4. The method of claim 1, wherein the custom content resource is a resource uploaded to the search engine by the user.

5. The method of claim 4, wherein determining the score for the custom content search result comprises determining the score using one or more user-specified ranking parameters selected by the user, the user-specified ranking parameters including the indication of relative importance of the custom content resource.

6. The method of claim 4, comprising receiving, from the user, a selection of the indication of relative importance as one of the user-specified ranking parameters for ranking custom content resources.

7. The method of claim 1, comprising:

presenting the custom content resources exposed to the search engine by the user in a custom content rating window; and

receiving the indication of relative importance of the custom content resource by user selection through the custom content rating window.

8. The method of claim 1, comprising:

receiving a designation from the user of a set of resources to be indexed separately in the custom search index.

9. The method of claim 1, wherein the custom content resources include documents, emails, files, collections of files, videos, or images.

10. A system comprising:

one or more computers and one or more storage devices storing instructions that are operable, when executed by the one or more computers, to cause the one or more computers to perform operations comprising;

receiving a search query requesting a search of a collection of custom content resources, wherein resources in the collection of custom content resources are resources exposed to a search engine by a user;

obtaining a custom content search result that the search engine has identified in response to the search query using a custom search index generated from the collection of custom content resources;

obtaining an indication of relative importance for a custom content resource identified by the custom content search result, the indication of relative importance being an indication of the importance of the custom content resource relative to other resources in the collection of resources and being assigned by the user that exposed the custom content resource to the search engine;

determining a score for the custom content search result based on the indication of relative importance for the custom content resource; and

ranking the custom content search result with one or more other custom content search results that were identified by the search engine in response to the received query, using the determined score.

11. The system of claim 10, wherein the operations further comprise receiving, by user input from the user, the indication of relative importance for the custom content resource, including receiving a user selection of one of at least two different indications of relative importance for the custom content resource.

12. The system of claim 10, wherein the indication of relative importance is an annotation to the custom content resource assigned by the user that exposed the custom content resource to the search engine.

13. The system of claim 10, wherein the custom content resource is a resource uploaded to the search engine by the user.

14. The system of claim 13, wherein determining the score for the custom content search result comprises determining the score using one or more user-specified ranking parameters selected by the user, the user-specified ranking parameters including the indication of relative importance of the custom content resource.

15. The system of claim 13, wherein the operations further comprise receiving, from the user, a selection of the indication of relative importance as one of the user-specified ranking parameters for ranking custom content resources.

16. The system of claim 10, wherein the operations further comprise:

presenting the custom content resources exposed to the search engine by the user in a custom content rating window; and

receiving the indication of relative importance of the custom content resource by user selection through the custom content rating window.

17. The system of claim 10, wherein the operations further comprise:

receiving a designation from the user of a set of resources to be indexed separately in the custom search index.

18. The system of claim 10, wherein the custom content resources include documents, emails, files, collections of files, videos, or images.

19. A computer program product, encoded on one or more non-transitory computer storage media, comprising instructions that when executed by one or more computers cause the one or more computers to perform operations comprising:

receiving a search query requesting a search of a collection of custom content resources, wherein resources in the collection of custom content resources are resources exposed to a search engine by a user;

obtaining a custom content search result that the search engine has identified in response to the search query using a custom search index generated from the collection of custom content resources;

obtaining an indication of relative importance for a custom content resource identified by the custom content search result, the indication of relative importance being an indication of the importance of the custom content resource relative to other resources in the collection of resources and being assigned by the user that exposed the custom content resource to the search engine;

determining a score for the custom content search result based on the indication of relative importance for the custom content resource; and

ranking the custom content search result with one or more other custom content search results that were identified by the search engine in response to the received query, using the determined score.
