在Wordpress中的查询集中使用运算符LIKE

Question

i have the next code

if(isset($_GET['f_search'])){
    $s_str = trim($_GET['f_search']);
    if(strlen($s_str) >= 3){
        $query->set('s', $s_str );
    }
}

This already work for search exact word, but if i want search example: 'Soccer' or 'Soccer-fine', i get different results, i want use operator LIKE for give me similar results but i dont know how use it, maybe

$query->set('s', 'LIKE', $s_str );

or something like that.

I use this in pre_get_posts of the archive page.

Thanks for the help, regards.
