* * Be structured as valid JSON.
* * Contain a valid query expression.
*
* Using a selector is significantly more efficient than using a JavaScript filter function, and is the recommended
* option if filtering on document attributes only.
*
* Elementary selector syntax requires you to specify one or more fields, and the corresponding values required for
* those fields. You can create more complex selector expressions by combining operators.
*
* Operators are identified by the use of a dollar sign `$` prefix in the name field.
*
* There are two core types of operators in the selector syntax:
* * Combination operators: applied at the topmost level of selection. They are used to combine selectors. In addition
* to the common boolean operators (`$and`, `$or`, `$not`, `$nor`) there are three combination operators: `$all`,
* `$elemMatch`, and `$allMatch`. A combination operator takes a single argument. The argument is either another
* selector, or an array of selectors.
* * Condition operators: are specific to a field, and are used to evaluate the value stored in that field. For
* instance, the basic `$eq` operator matches when the specified field contains a value that is equal to the supplied
* argument.
* * Only equality operators such as `$eq`, `$gt`, `$gte`, `$lt`, and `$lte` (but not `$ne`) can be used as the basis
* of a query. You should include at least one of these in a selector.
*
* For further reference see
