* Queries this collection, returning an array or a MongoDBCursor for the result set.
* @param array $criterion Associative array with fields to match.
* @param array $projection Fields of the results to return. The _id field is always returned.
* @param array $sort_by An array of fields by which to sort.
* Each element in the array has as key the field name,
* and as value either 1 for ascending sort, or -1 for descending sort.
* Each result is first sorted on the first field in the array,
* then (if it exists) on the second field in the array, etc.
* This means that the order of the fields in the fields array
* is important.
* @param int $skip The number of matching documents to skip before returning results.
* @param int $limit The maximum number of matching documents to return.
* @param boolean $to_array Whether it should return an array instead of a MongoDBCursor.
* @return array|MongoDBCursor Returns an array or a cursor for the results
* matching the criterion.
