  • Publication number: 20230267151
    Abstract: A refinement option recommendation system provides suggestions for completed search queries and refinement options. Upon receiving, at a search engine for a site, a portion of a search query from a user, the refinement option recommendation system determines a completed search query based on the portion of the search query. For example, if the portion includes “bak” or “baking,” the completed search query suggestion may include “baking recipe books” or “baking ingredients.” The refinement option recommendation system also determines a refinement option associated with the completed search query based on historical queries. For example, the refinement option may include recipe books associated with a particular culture based on historical queries by the user or by other users. As such, a first suggestion for the completed search query and a second suggestion for the refinement option are both provided to the user.
