2dsphere Index

Create a 2dsphere Index

db.collection.createIndex() method is used to create a  2dsphere index.  The blueprint of a 2dsphere index :
 

db.collection.createIndex ( { <location field> : "2dsphere"  } )

 

Here, the  location field  is the key and  2dsphere  is the type of the index. In the following example we are going to create a  2dsphre  index in the  places collection.

db . places.insert (
{
loc : {  type:  "Point",  coordinates: [ -73.97, 40.77  ] },
name:  "Central Park",
category :  "Parks"
})

 

The following operation will create 2dsphere index on the loc field of places collection.

db.places.createIndex ( {  loc : "2dsphere"  } )
