<?php

function my_searchwp_search_regex_whitelist_exclusivity( $terms, $engine ) {
	global $searchwp;
	
	// we want to strip out any partial matches
	
	$terms = ' ' . $terms . ' ';
	$whitelisted_terms = $searchwp->extract_terms_using_pattern_whitelist( $terms );
	$terms = str_replace( ' ', '  ', $terms );

	// remove the matches
	if( ! empty( $whitelisted_terms ) ) {
		$terms = str_ireplace( $whitelisted_terms, ' ', $terms );

	// clean up the double space flag we used
	$terms = str_replace( '  ', ' ', $terms );
	$terms = trim( $terms );
