       mongoc_matcher - Client Side Document Matching

BASIC DOCUMENT MATCHING (DEPRECATED)

       WARNING:
          This feature will be removed in version 2.0.

       The MongoDB C driver supports matching a subset of the MongoDB query specification on the client.

       Currently,  basic numeric, string, subdocument, and array equality, $gt, $gte, $lt, $lte, $in, $nin, $ne,
       $exists, $type, $and, and $or are supported. As this is  not  the  same  implementation  as  the  MongoDB
       server, some inconsistencies may occur. Please file a bug if you find such a case.

       To test this, perform a mongodump of a single collection and pipe it to the program.

          $ echo "db.test.insert({hello:'world'})" | mongo
          connecting to: test
          WriteResult({ "nInserted" : 1 })
          bye

          $ mongodump -d test -c test -o - | filter-bsondump
          { "_id" : { "$oid" : "537afac9a70e5b4d556153bc" }, "hello" : "world" }
