Enum IndexType

Specifies the different index types which are available for index creation.

Enum members

Name	Description
geoHaystack	A geoHaystack index is a special index that is optimized to return results over small areas. geoHaystack indexes improve performance on queries that use flat geometry. See Also https://docs.mongodb.com/manual/core/geohaystack/
hashed	To support hash based sharding, MongoDB provides a hashed index type, which indexes the hash of the value of a field. These indexes have a more random distribution of values along their range, but only support equality matches and cannot support range-based queries. See Also https://docs.mongodb.com/manual/core/index-hashed/
legacy2D	Legacy 2D plane index used in MongoDB 2.2 and earlier. Doesn't support GeoJSON objects. Uses planar geometry to return results. See Also https://docs.mongodb.com/manual/core/2d/
sphere2D	2D sphere index that calculates geometries on an earth-like sphere. Supports storing as GeoJSON objects. See Also https://docs.mongodb.com/manual/core/2dsphere/
text	Creates a text index which supports searching for string content in a collection. These text indexes do not store language-specific stop words and stem the words in a collection to only store root words. See Also https://docs.mongodb.com/manual/core/index-text/
