Systems and methods are disclosed herein for providing search results, particularly product records from a product database. Past queries are analyzed and grouped into clusters according to similarities with one another. For an individual query, relevant search results are identified and departments corresponding thereto are also identified. Confidence scores are determined for the identified departments and if one or more departments have confidence scores above a threshold, the search results are filtered based thereon. If not, then departments corresponding to a query cluster relevant to the query are selected. Additional departments may also be selected based on the number of search results corresponding to the additional departments. Search results filtered according to one or more selected departments are transmitted to an author of the query.
