Systems and methods for performing multi-index searches are described in which a search string may be received, and processed by first running the query through a general search index, such as an Internet or e-commerce search. The results of the general search may then be analyzed to determine an appropriate context for the search query, e.g. clothing, sports, games, etc. The search query may then be processed using a second search index that is tuned to the specific context of the search query. After obtaining the results to the second search, the second search index and/or ranking algorithms may be modified to improve future search results having a similar context.
