ABSTRACT:
A first search is performed in response to a received search query. The first search is based at least in part on a first portion of the search query. In the first search, a first set of content items are searched over to identify a first set of search results. Each result in the first set of search results identifies at least one content item of the first set of content items. A second set of content items for performing a second search is determined based at least in part on one or more of the results in the first set of search results. The second set of content items includes content items not included in the first set of search results. A second search is performed, searching over the second set of content items to identify a second set of search results. The second search is based at least in part on a second portion of the search query. Each result in the second set of search results identifies at least one content item of the second set of content items.
