searchwp_max_search_terms

To respect performance, SearchWP limits the number of search terms that are considered when running searches. You can modify that limit with this filter.

Example: To limit ALL search queries to 5 terms, add the following to your active theme’s functions.php:

	<?php

	function my_searchwp_max_search_terms( $maxTerms, $engine ) {
	// limit to 5 search terms
	return 5;
	}
	add_filter( 'searchwp_max_search_terms', 'my_searchwp_max_search_terms', 10, 2 );

Example: To limit all supplemental search engine search queries to 7 terms, add the following to your active theme’s functions.php:

	<?php

	function my_searchwp_max_search_terms_supplemental( $maxTerms, $engine ) {
	// limit to 7 search terms for all supplemental search engines, not the default
	return 7;
	}

	add_filter( 'searchwp_max_search_terms_supplemental', 'my_searchwp_max_search_terms_supplemental', 10, 2 );

	// limit to 8 search terms for My Supplemental Search Engine ONLY
