getMatchingIds() public method

If no entries have been found, the result is an empty array. If no filtering was applied and therefore all ids shall be reported as valid, the return value of NULL is allowed. The OR filter rule has an embedded shortcut for the first rule that returns "null". When this happens, no further child rules will get evaluated, as the result set can not expand any further. Note: when "stopAfterMatch" has been set, the rule will stop processing also when the first rule returns a non empty result and return that result.
