Replace/Mute/Stop Search Query

I’m trying to replace the search functionality in WP.

I’ve already created the search.php template with all the results I want to display.

I don’t want any results from the WP database. I just want to show my results in search.php using the native searchform.php and the native ?s=keyword URL structure.

Doing that because of SELECT SQL_CALC_FOUND_ROWS wp_posts.ID FROM wp_posts ... search built in query with is very CPU consuming.

So in my themes functions.php I added:

add_action('pre_get_posts', 'no_search_query'); function no_search_query($  query) {     if($  query->is_search() && $  query->is_main_query() && get_query_var('s', false)) {         unset( $  query->query_vars['s'] );         $  query->set( 'post__in', '' );     } } 

and added:

$  is_search_query = ($  _GET["s"]) ? ($  _GET["s"]) : 0; 

to my search.php to get the search keyword.

This actually did the trick but the query is still being called.

SELECT SQL_CALC_FOUND_ROWS wp_posts.ID FROM wp_posts  WHERE 1=1  AND wp_posts.post_type IN ... 

The call to the database is now a lot of less consuming (there are no arguments) but its still a call to the database which I want to eliminate.

Any idea how to do that?

Best regards.
