MongoDB Text Index on all Fields using Java

Question

I want to create a text index on all of my fields in MongoDB. I know that it can be done like this:

db.collection.ensureIndex({ "$**": "text" },{ name: "TextIndex" })

But I want create this index in my Java program. I tried with this:

collection.createIndex(new BasicDBObject("$**","text"),newBasicDBObject("name","TextIndex"));

but it gave me this error: com.mongodb.MongoException: Can't canonicalize query: BadValue unknown operator: $**

I don't know what to do. I can see that others have asked the similar question but no one answered. Can any of you guys help me?

Thanks in advance.

Text search is a rather new feature. Are you maybe using an outdated version of the java driver? Or maybe even of MongoDB itself? Text search must be enabled through a config parameter in 2.4 and doesn't exist in prior versions. — Philipp

Yes I know. Both my MongoDB and Java driver are their latest release. I can create an index on one field and it's working but I want to create index on all fields. — NEO

Oh, it seems that my Java Driver was not actually the latest release. I got the newest release and now it works like a charm. — NEO

Oops, it seems that my Java Driver was not actually the latest release. I got the newest release and now it works like a charm.

Always download your libs from the maven repos.
