Query Syntax in mongodb for sql "like" - i am using java

Question

basically this is my question: How to query MongoDB with "like"?

but i guess all the answers in here are applicable when you are using mongodb shell command line, so what is the equivalent for db.users.find({"name": /.*m.*/}) when we are using java.

here is how i am trying to do

  DBCollection coll = MongoDBUtil.getDB().getCollection("post_details");      
    BasicDBObject query = new BasicDBObject();      
    query.put("price", new BasicDBObject("$gt", 5).append("$lt", 8));

    /*what should i write instead of this line*/ 
            query.put("title", "/.*m.*/");

    DBCursor cur = coll.find(query);

Answer 1

For this issue you should use a regex as in this example:

BasicDBObject query = new BasicDBObject();
Pattern regex = Pattern.compile("the title you are looking for"); // should be m in your case
query.put("title", regex);

Answer 2

Taking the above example as reference, but using the Filters class:

Pattern regex = Pattern.compile("title you look for");
Bson filter = Filters.eq("nombre", regex));
