Query posts by categories and tags using free text search
I’m currently building my own search results page which takes a value from the URL. I’m able to query the post title easily enough by using the S parameter however I’m wondering how I could expend this to also query categories, tags and the maybe the excerpt?
Obviously, as the value is from a text input it’s going to have to be some kind of “LIKE” query.
If someone could point me in the right direction I really appreciated it.
$args = array ( 'post_type' => 'post', 'post_status' => 'publish', 's' => $_REQUEST['terms'], 'posts_per_page' => 12, 'orderby' => 'title', 'order' => 'ASC' );
