Search end point doesn’t use elastic search

Hello,

I’m using elastic press 3.6 and elastic search 7.15. and WordPress in back and React in front.

I’ve create a custom endpoint with wp query.

Args of my query are :

$args = array(
        's' => $s,
        'post_type' => $post_type,
        'ep_integrate' => true,
        'posts_per_page' => -1
    );

I’ve the param : ‘ep_integrate’ => true, but when I check results of this query I’vent results from elastic search.

for exemple, I use a word put in tags for my search. If I do query on elastic search I’ve results (post with this tag), but when I do this in wordpress endpoint, I’vent result.

So I think elastic search is not used in this in this query.

Thanks for your help
