By default, WordPress searches by keyword. What this means is that when passed the search query "Loren Ipsum", WordPress builds the following for the WHERE clause:

((wp_posts.post_title LIKE '%Loren%') OR
(wp_posts.post_content LIKE '%Loren%')) 
AND
((wp_posts.post_title LIKE '%Ipsum%') OR
(wp_posts.post_content LIKE '%Ipsum%'))

This answer can be helpful to you ! There is also a plugin for this : Search Everything

Depends how you would like to do it. I am currently building a site with a custom search. I did it in a couple of steps.

  • Think about prefered url: www.example.com/search/< product_name >
  • Create a wordpress template for your custom search.
  • Add a page with the coresponding template. Note the pages id
  • Add the needed rewrite tags for it. You will use them later in your search template:

    add_action('init','custom_rewrite_tags');
    
    function custom_rewrite_tags() {
        add_rewrite_tag('%var%','([^&]+)');
    }
    
  • Now you can create your rewrite so the search is a pretty url to your liking

    add_action('admin_init','action_custom_rewrite_rules');
    function action_custom_rewrite_rules() {
        add_rewrite_rule('^search/([^&]+)/?$','index.php?page_id=<the page id>&var=$matches[1]','top'); 
    }
    

    The add rewrite rule specifies the regex to match for the url, and the coresponding query it will send to index.php. The regex captures are remmemberd in the $matches variable, starting from index 1 the first captured group. In this case whatever is www.example.com/search/< here >/ . We assign the matches to your custom rewrite tag.

  • Now in your search template you can start a function and it will have access to the rewrite tags. Example, will return your variable. If you don't like pretty url-s you can always search with a get_query:

    /*
     * Template name: Custom Search Template
     */
    $var = get_query_var('var');
    
  • And now the query

    $sql = $wpdb->prepare("SELECT * FROM myTable WHERE var = %s",
        $var);
    $results = $wpdb->get_results($sql);
    

And in results you have your results, do whatever you want with them.
