Location-Based Search Refinements

摘要

A method includes receiving a search query and one or more context parameters from a user device. The search query indicates a search string. The method includes determining a search area based on at least one of the search string or the one or more context parameters, and obtaining a set of point of interest records based on the search area. The method includes clustering the point of interest records into clusters based at least on locations of the respective points of interest and generating one or more location-based refinements based on the clusters of the of point of interest records. Each location-based refinement is based on one of the clusters of the point of interest records and includes a display portion and a refined search query that is constrained by the refined search area. The method includes transmitting the one or more location-based refinements to the user device.

1. A method comprising:
receiving, at data processing hardware, a search query related to a point of interest search on a user device; determining, by the data processing hardware, a search area based on the search query; identifying, by the data processing hardware, points of interest in the search area; generating, by the data processing hardware, one or more location-based refinements based on the search query and the identified points of interest in the search area, each location-based refinement being a modification of the search query that includes a geographical location constraint narrowing the search area; and transmitting the one or more location-based refinements from the data processing hardware to the user device.
