The new feature in Full Text Search (FTS) allows for geo bounded polygon query capabilities, enabling more precise results by specifying region boundaries in a granular way, rather than relying on simple rectangular or square regions. This feature adds the capability to perform random bounding polygon queries to select documents within a polygon area, using an array of coordinate pairs representing vertices that define the polygon area. The search process involves indexing documents with geolocation fields, identifying a polygon area, and trying the query in any geoJSON format, such as specifying coordinates in an anticlockwise direction or using a closed format. The feature uses ray casting technique for finding point inclusivity within the polygon and does not support holes in polygons, but users can perform such queries using boolean queries with a must_not clause.
