<p>Methods and systems for providing a geo-search engine capability for large point-of-interest record datasets are disclosed. These methods and systems employ a Partition-by-Query index containing key-values pairs corresponding to keys reflecting concept-ordered geo-search phrases and values reflecting ordered lists of point-of-interest record references that are responsive to the concept-ordered geo-search phrase in a corresponding key. A large Partition-by-Query index may be partitioned across multiple servers depending on the size of the index, or the size of the index may be reduced by compressing query-references pairs into clusters. The methods and systems described herein may provide suggestions and spelling corrections to the user, thereby improving the user's geo-search engine experience while meeting user expectations for geo-search quality and responsiveness.</p> |
