GENERATION OF REFINEMENT TERMS FOR SEARCH QUERIES

A computer-implemented method includes receiving from a user, by a search system, a search query comprising terms. Using at least one association graph comprising terms, the search system generates a suggested replacement query by designating one or more of the terms of the search query as anchor terms, and the remaining terms of the search query as non-anchor terms, and replacing one or more of the non-anchor terms of the search query with one or more suggested replacement terms, to generate the suggested replacement query that includes the one or more anchor terms and the one or more suggested replacement terms. The suggested replacement query is presented to the user. Responsively to a selection of the suggested replacement query by the user, the search query received from the user is replaced with the suggested replacement query, and search results are generated responsively to the suggested replacement query and presented.
