MongoDB Text Index using Java Driver

Question

Using the MongoDB Java API, I have not been able to successfully locate a full example using text search. The code I am using is this:

DBCollection coll;
String searchString = "Test String";

coll.createIndex(new BasicDBObject ("blogcomments", "text"));
DBObject q = start("blogcomments").text(searchString).get();

The name of my collection that I am performing the search on is blogcomments. creatIndex() is the replacement method for the deprecated method ensureIndex(). I have seen examples for how to use the createIndex(), but not how to execute actual searches with the Java API. Is this the correct way to go about doing this?

That's not quite right. Queries that use indexes of type "text" can not specify a field name at query time. Instead, the field names to include in the index are specified at index creation time. See the documentation for examples. Your query will look like this:

DBObject q = QueryBuilder.start().text(searchString).get();
