searchwp_include

Use this filter to define the pool of potential results SearchWP can use when running searches.

Example: To directly limit searches to three specific posts, add the following to your active theme’s functions.php:

	<?php

	function my_searchwp_include_three_posts( $ids, $engine, $terms ) {
	// make sure searches are limited to posts 134, 188, and 189
	return array( 134, 188, 189 );
	}

	add_filter( 'searchwp_include', 'my_searchwp_include_three_posts', 10, 3 );

	$categoryID = 10;

	$args = array(
	'category' => $categoryID,
	'fields' => 'ids',
	'nopaging' => true,
	);
