Performance

To increase search speed, it's better to create index in mongodb. However, creating index may take long time.

$ mongo
MongoDB shell version: 3.0.4
connecting to: test
> 
> use MDP
switched to db MDP
>
> db.behavior.createIndex({"$**":"text"},{name:"TextIndex"})
{
  "createdCollectionAutomatically" : false,
  "numIndexesBefore" : 1,
  "numIndexesAfter" : 2,
  "ok" : 1
}
>
