    Hi,
    First, I like what your plugin does and I want to thank you for making it available to us.

    Here’s my problem. I’d like to add a modifier that allows me to search for posts/pages by categories. Something like -categ {category name}. Being somewhat limited in PHP I tried my hand at it but I’m not having too much success. Would you mind helping me please?

    Here’s what I wrote:

    add_filter( 'better_internal_link_search_modifier-categ', 'bils_category_search', 10, 2 );
function bils_category_search( $results, $args ) {
		$pts = get_post_types( array( 'public' => true ), 'objects' );
		$pt_names = array_keys( $pts );
		$categories = get_terms( 'category' );
		$searched_cat = $args['s'];

 if ( $searched_cat == $categories->name){
	  $cat = $categories->term_id;
  }

	$search_args = array(
		'post_status' => 'any',
		'post_type' => $pt_names,
		'category' => $cat,
		'paged' => $args['page'],
		'posts_per_page' => $args['per_page'],
		's' => $args['s']
	);	

	$posts = get_posts( $search_args );
	if ( $posts ) {
		foreach ( $posts as $post ) {
			$results[] = array(
				'ID' => $post->ID,
				'title' => trim( esc_html( strip_tags( get_the_title( $post ) ) ) ),
				'permalink' => get_permalink( $post->ID ),
				'info' => $pts[ $post->post_type ]->labels->singular_name,
			);
		}

	}
	return $results;

}

    I also mofified the help section part by adding a part in the array:
    `’categ’ => array(
    ‘title’ => ‘<strong>-categ {query}</strong></span><span class=”item-description”>Search your local WordPress installation for posts of that category.</span>’,
    ‘permalink’ => home_url( ‘/’ ),
    ‘info’ => ‘Local’
    ),`

    Hi Sophie,

    You were close! It sounds like you want to search for posts within a particular category, so you need to input a couple of things: The category and the search query. Here’s a snippet based on your code that does this. And here’s the syntax:

    -categ:{category slug} {query}

    If needed, you can also search across multiple categories by separating their slugs with commas: -categ:{cat1,cat2,cat3,etc}

    I also included the help text via a filter so that your modifications won’t be wiped out when the plugin is updated in the future. I’d recommend dropping the new snippet from the link above in a separate plugin of your own, but it will work in your theme’s functions.php file as well.
