/**
* A mapping of search operators to their corresponding processing functions.
*
* This `Map` associates an operator key (e.g., `$eq`, `$gt`) with a function that processes the search parameter,
* modifies the `queryArray`, and populates the `values` array with the appropriate values for the SQL query.
*
* @property $custom - Processes a custom operator, pushing the key and value to the `queryArray` and `values` respectively.
* @property $eq - Processes an equality check (`=`), handling both regular and `NULL` values.
* @property $gt - Processes a greater-than comparison (`>`).
* @property $gte - Processes a greater-than-or-equal comparison (`>=`).
* @property $in - Processes an inclusion check (`IN`), pushing the array of values.
* @property $json - Processes a JSON equality check.
* @property $like - Processes a pattern match (`LIKE`).
* @property $ilike - Processes a case-insensitive pattern match (`ILIKE`).
* @property $lt - Processes a less-than comparison (`<`).
* @property $lte - Processes a less-than-or-equal comparison (`<=`).
* @property $ne - Processes a not-equal comparison (`<>`), handling both regular and `NULL` values.
* @property $nin - Processes a not-inclusion check (`NOT IN`).
* @property $between - Processes a range check (`BETWEEN`).
* @property $nbetween - Processes a not-in-range check (`NOT BETWEEN`).
* @property $nlike - Processes a not-like pattern match (`NOT LIKE`).
* @property $nilike - Processes a not-ilike pattern match (`NOT ILIKE`).
