NAME¶

mongoc_matcher - Client Side Document Matching

BASIC DOCUMENT MATCHING (DEPRECATED)¶

WARNING:

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" }
