1. A method performed by one or more computing devices, the method comprising: obtaining, by at least one of the one or more computing devices, a search query; obtaining, by at least one of the one or more computing devices, product search results based on the search query and a products search index that includes information regarding documents associated with products; determining, by at least one of the one or more computing devices, a category associated with a set of results of the product search results; identifying, by at least one of the one or more computing devices, candidate queries for the search query; determining, by at least one of the one or more computing devices, whether the category matches one of the candidate queries; determining, by at least one of the one or more computing devices, a first ratio based on a first quantity of times that the search query is submitted to a web search engine interface; determining, by at least one of the one or more computing devices, a second ratio based on a second quantity of times that the search query is submitted to a specialized search engine interface that is used to search for information associated with a type of media or to search for information associated with news; identifying, by at least one of the one or more computing devices and based on the first ratio and the second ratio, that the search query is associated with the type of media identified by the category when the category matches one of the candidate queries; and providing, by at least one of the one or more computing devices and based on identifying that the search query is associated with the type of media, a result document based on the type of media.

The method of claim 1 , where identifying that the search query is associated with the type of media includes: determining whether the candidate queries match words in a keyword list associated with the type of media, and identifying, based on the first ratio and the second ratio, that the search query is associated with the type of media when the category matches one of the candidate queries and when the candidate queries match the words in the keyword list.
