## Major New Features 

The following changes in MongoDB affect both standard and Enterprise editions: 

## Text Search 

Add support for text search of content in MongoDB databases as a beta feature. See Text Indexes (page 500) for more information. 

## Geospatial Support Enhancements 

• Add new 2dsphere index (page 496). The new index supports GeoJSON 792 objects Point , LineString , and Polygon . See 2dsphere Indexes (page 496) and Geospatial Indexes and Queries (page 494). 

• Introduce operators $geometry , $geoWithin and $geoIntersects to work with the GeoJSON data. 

## Hashed Index 

Add new hashed index (page 502) to index documents using hashes of field values. When used to index a shard key, the hashed index ensures an evenly distributed shard key. See also Hashed Shard Keys (page 674).
