node.js - runCommand equivalent for nodejs-native-mongodb

I'm trying to utilize MongoDB 2.4 experimental text search feature from within nodejs. The only problem is, native nodejs mongo drivers don't seem to support collection-level runCommand, as far as I can tell.

The Mongo shell syntax looks like this:

db.collection.runCommand( "text", { search : "Textvalue" } );

There is a db.command / db.executeDbCommand function it appears, but I don't know how to choose a collection and run the text command using it (if it is possible), as it needs to be on the collection level and not the db level.

Any help would be appreciated

this.db.command({text:"collection" , search: "phrase" }, function(err, cb){
