8. A device comprising: a memory to store instructions; and a processor to execute the instructions to: receive first information indicating that a pair of queries is associated with a threshold quantity of search results that are common between the pair of queries, a first query, in the pair of queries, including an extra term that is not included in a second query in the pair of queries; receive, based on receiving the first information indicating that the pair of queries is associated with the threshold quantity of search results that are common between the pair of queries, second information indicating that the extra term is not significant; receive third information indicating that another pair of queries is not associated with the threshold quantity of search results that are common between the other pair of queries, a first query, in the other pair of queries, including the extra term and a second query, in the other pair of queries, not including the extra term; receive, based on receiving the third information indicating that the other pair of queries is not associated with the threshold quantity of search results that are common between the other pair of queries, fourth information indicating a context in which the extra term is significant, the context in which the extra term is significant being based on the information indicating that the pair of queries is associated with the threshold quantity of search results that are common between the pair of queries; and store information including the extra term, an indication that the extra term is not significant, and the context in which the extra term is significant.
14. The device of claim 8 , where the processor is further to: identify, based on the second information, a plurality of documents based on the first query; and associate a first weight to the extra term; associate a second weight to one or more other terms in the first query, the second weight being greater than the first weight; and score, based on the associated first weight and the associated second weight, the plurality of documents.
