       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" }
