 **You don't need to know anything about MongoDB** in order to use CASL, you need to know only subset of its query language operators.

-We can combine any amount of fields inside single query, all their restrictions are tested according to `AND` logic. If we do not specify operator, the query uses `$eq` operator (equality operator). So, a query like `(2)` matches objects if their `private` and `hidden` property values equal to `false` (i.e., `!object.private && !object.hidden`).

 We can specify multiple operators for the same field, in this case each operator must return `true` to match a field value. So, `(3)` matches objects only if `price` property value is between 10 and 50 inclusively (i.e., `object.price >= 10 && object.price <= 50`).
