Search by Exact Words in WordPress Search

Improve WordPress Search to Make it Search Exact Words.

The native wordpress search, does not look for exact complete words. It means that when you look for ‘Los’ you also get words like ‘lost’ ‘loser’ in search results. I found a lot of plugins which can improve search but found glitches in each of it. I decided to write my own solution. I needed a search which could look for exact word in posts. I implemented wordpress search for exact word in post titles using this code in functions.php.

// Search SQL filter for matching against post title only.
function __search_by_title_only( $search, $wp_query )
global $wpdb;

if ( empty( $search ) )
return $search; // skip processing - no search term in query

$q = $wp_query->query_vars;
$n = ! empty( $q['exact'] ) ? '' : '%';

$search =
$searchand = '';

foreach ( (array) $q['search_terms'] as $term ) {
$term = esc_sql( like_escape( $term ) );

$search .= "{$searchand}($wpdb->posts.post_title REGEXP '[[:<:]]{$term}[[:>:]]')";

$searchand = ' AND ';

if ( ! empty( $search ) ) {
$search = " AND ({$search}) ";
if ( ! is_user_logged_in() )
$search .= " AND ($wpdb->posts.post_password = '') ";

return $search;

add_filter( 'posts_search', '__search_by_title_only', 1000, 2 );

You can change this to search for exact words in titles plus content both, by modifying the line 18 to
Method 1:

$search .= "{$searchand}($wpdb->posts.post_title REGEXP '[[:<:]]{$term}[[:>:]]') OR ($wpdb->posts.post_content REGEXP '[[:<:]]{$term}[[:>:]]')";

The rest of code will remain same. Using the above snippets you will be able to improve wordpress search and make it exact word search.

I have come across another simpler solution, which be helpful, but the snippet posted above can be customized easily as much you need. So I would use method 1.

Method 2:

add_action('pre_get_posts', 'my_make_search_exact', 10);
function my_make_search_exact($query){

    if(!is_admin() && $query->is_main_query() && $query->is_search) :
        $query->set('exact', true);

    Thank you;

    You saved me so much time you have no idea! I truly appreciate that. Just for the future reference and those who are cutting/pasting the code as is, You may need to change a few HTML special characters like & to & or > to > signs. Also, there is a ” missing at the end of the line 18.

    Great code.

          Hi Carlos,
          Thanks. That can be done by changing the action url of search form to

          <form role="search" method="get" id="searchform" action="put_the_above_url_here">

          where ‘mycat’ is the category i want to search for those words. Hope this helps.

    I search “F” and get John F. Kennedy, F-1, F.D.R., etc.
    I mean some chars such as coma, dot, etc. still follow.

    BTW, thank you.. this helps me much.

    Thank you for your fantastic code, it really saved me!

    Taking this a step further you can also add taxonomy names to the “exact-match search” by replacing the existing line with the following:

    $search .= “{$searchand}(
    $wpdb->posts.post_title REGEXP ‘[[::]]’)
    OR ($wpdb->posts.post_content REGEXP ‘[[::]]’)
    OR ((SELECT COUNT(wp_terms.term_id) FROM wp_term_relationships
    LEFT JOIN wp_term_taxonomy ON wp_term_relationships.term_taxonomy_id = wp_term_taxonomy.term_taxonomy_id
    LEFT JOIN wp_terms ON wp_term_taxonomy.term_id = wp_terms.term_id
    WHERE (wp_term_relationships.object_id = $wpdb->posts.ID)
    AND ( REGEXP ‘[[::]]’)) > 0)

    This particularly helps if you are trying to find WooCommerce products by category, as the existing code does not find them.

    I hope others find this useful.

    I’m using this code and it lists posts whose titles contain an exact match, but I also require all other non-exact matches to be listed after the exact matches.

    For example, if I search “ABC”, this code will list posts with titles like “ABC” and “ABC 1”. But I also need it to list posts with titles like “ABCD” after all the exact matches.

    Is there a way to modify this code so that it “defaults” to non-exact matches after all the exact matches have been listed?

    Thank you, and thanks for the helpful post.

    Hi. Is there a way we can narrow down search within only 2-3 first words in title?
    My posts title look like this (they contain name of company and keywords):
    Flower in you Ltd. | A florist and arranger shop Flower box, flower decorations, wedding bouquets, funeral wreaths, flower delivery, gift arrangements, weddings, decorations for celebrations, decorations of business premises, innovative flower decorations, dry and fresh flowers, florist services in Samobor.
    I would like to achieve a search box that would search by the title of company exclusively and since in post title there is company name and keywords..Can this be done?
