Query Modifiers

In addition to the MongoDB Query Operators, there are a number of "meta" operators that let you modify the output or behavior of a query.

Note
Deprecated in the mongo Shell since v3.2
Starting in v3.2, the query "meta" operators are deprecated in mongosh. In mongosh, use the cursor methods instead.

The driver interfaces may provide cursor methods that wrap these options. When possible, use these methods; otherwise, you can add these options using either of the following syntax:

db.collection.find( { <query> } )._addSpecial( <option> )
db.collection.find( { $query: { <query> }, <option> } )
