Abstract: Systems, methods, and computer-readable media for search query improvement. A method includes receiving, by a processing device, a set of search queries; generating, by the processing device, a cluster similarity score for the set of search queries based on a similarity index, wherein the similarity index is configured to consider each search term of one or more search queries of the set of search queries; determining, by the processing device, based on the similarity score, a success outcome of the set of search queries; and displaying, on a display device, at least one of the similarity score, the success outcome, or other scores or metrics associated with the set of search queries.
