Client Side Document Matching
Description
MONGOC_MATCHER
NAME
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" }
