8. One or more devices comprising: one or more processors; and one or more memories including a plurality of instructions that, when executed by the one or more processors, cause the one or more processors to: analyze query logs to identify a pair of queries that are the same except that a first query, in the pair of queries, includes an extra term that is not included in a second query in the pair of queries; identify whether the pair of queries is associated with a quantity of search results that are common or different between the pair of queries; identify the extra term as a term that is not significant when the pair of queries is associated with at least a first threshold quantity of search results that are common between the pair of queries; identify the extra term as a term that is significant when the pair of queries is associated with at least a second threshold quantity of search results that are different between the pair of queries; and process a query that includes the extra term based on identifying the extra term as a term that is not significant or as a term that is significant, the query being processed differently based on whether the extra term is identified as a term that is not significant or a term that is significant.

The one or more devices of claim 8 , where the one or more processors are further to: determine, after identifying the extra term as not significant when the pair of queries is associated with at least the first threshold quantity of search results that are common between the pair of the queries, whether a context exists in which the extra term is significant.
