Mongodb ensureIndex

Question

I am working on Mongodb where I am trying to do the indexing on my collection, it is taking only the range between -140 to 3320000 then the total indexing is coming very high ie 23628640 (By using db.Location.totalIndexSize() )

Because of that my query is taking more time in execution.

How can I make the indexing between (-180 ,180)? please help me out

db.Location.ensureIndex({loc:"2d",type:1,clientId:1,background:true},{min:-140,max:3320000})

Answer 1

I think your syntax is wrong. You probably want:

db.Location.ensureIndex({loc:"2d",type:1,clientId:1}, {background:true})

The min and max options are optional and default to -180 and 180. Do you have any objects that fall outside of that range? It would be helpful to see the error you get and an example object.
