Hello I have a problem in my Java & mongodb web project. I am using Mongo Java Driver. I am doing text search. However when i use $meta operator with text search it gives this error:
com.mongodb.MongoQueryException: Query failed with error code 2 and error message 'unknown operator: $meta' on server localhost:27017

my code is:

FindIterable<Document> iterable = db.getCollection("users").find(
new Document("$text", new Document("$search", searchInput).append("$caseSensitive", false))
.append("score", new BasicDBObject("$meta", "textScore" )) );
