Undefined array key “post_type”

My site would not return any results for the word elementor. That code snippet fixed it.

And these are the settings. No permutation / combination would help to get any results for /?s=elementor

• This reply was modified 9 months ago by Shivanand Sharma. Reason: typo in query

Previous post in which I shared the settings has been held for moderation.

Your code does work as does the previous one I shared except that it throws that warning in the debug.log. Surprisingly the default post_type is only set to page. Why???

add_filter( 'relevanssi_modify_wp_query', function( $query ) {
        error_log( $query->get("post_type") ); //outputs page
        $query->set( 'post_type', 'any' );
        return $query;
} );
