geoHaystack Indexes
Important
Removed in MongoDB 5.0
MongoDB 5.0 removes the deprecated geoHaystack index and
geoSearch command. Use a 2d index with
$geoNear or one of the supported geospatial query
operators instead.
Upgrading your MongoDB instance to 5.0 and setting
featureCompatibilityVersion to 5.0 will delete any
pre-existing geoHaystack indexes.
