10 This feature will be removed in version 2.0.

12 The MongoDB C driver supports matching a subset of the MongoDB query
13 specification on the client.
14
15 Currently, basic numeric, string, subdocument, and array equality, $gt,
16 $gte, $lt, $lte, $in, $nin, $ne, $exists, $type, $and, and $or are sup‐
17 ported. As this is not the same implementation as the MongoDB server,
18 some inconsistencies may occur. Please file a bug if you find such a
19 case.

21 To test this, perform a mongodump of a single collection and pipe it to
22 the program.
23
24 $ echo "db.test.insert({hello:'world'})" | mongo
25 connecting to: test
26 WriteResult({ "nInserted" : 1 })
27 bye
