find a file by metadata using spring GridFsTemplate in MongoDB

Can i find a file by metadata using spring GridFsTemplate ?

For example by:

BasicDBObject query = new BasicDBObject("metadata.target_field", "abcdefg");

i find a topic

Is it possible or the best solution is to rewrite the GridFsTemplate ?

To solve this task in this way.

Mongo GridFs create two collections

  1. fs.chunks where files saved
  2. fs.files where metadata saved

so i create query using fs.files structure

 Query query = new Query();
        query.addCriteria(Criteria.where("metadata.yourdata").is(id));
        query.limit(1);
        query.with(new Sort(Sort.Direction.DESC, "uploadDate"));
