Custom WordPress Search Page URL Using Rewrite Rules

In this tutorial, we will introduce you the way to change wordpress search url.

For example, we plan to change

https://www.example.com/?s=lstm

to

https://www.example.com/model/lstm/

The full code is below:

add_filter( 'rewrite_rules_array','my_insert_rewrite_rules' );
add_filter( 'query_vars','my_insert_query_vars' );
add_action( 'wp_loaded','my_flush_rules' );

// flush_rules() if our rules are not yet included
function my_flush_rules(){
    $rules = get_option( 'rewrite_rules' );
    
    if ( ! isset( $rules['model/(.*)'] ) ) {
        global $wp_rewrite;
           $wp_rewrite->flush_rules();
    }
}



// Adding a new rule
function my_insert_rewrite_rules( $rules )
{
    $newrules = array();
    $newrules['^model/(.+)/page/?([0-9]{1,})/?$'] = 'index.php?s=$matches[1]&paged=$matches[2]';
    $newrules['^model/(.+)/?$'] = 'index.php?s=$matches[1]';

    return $newrules + $rules;
}

function my_insert_query_vars( $vars )
{
    array_push($vars, 's');
    return $vars;
}

You can copy and save this code in your theme functions.php

add_action( 'wp_loaded','my_flush_rules' );

This code will call my_flush_rules to flush wordpress rewrite rule.

my_insert_rewrite_rules function convert ?s=keyword to /model/keyword.

Then you will find the effect of https://www.example.com/?s=lstm and https://www.example.com/model/lstm/ is the same.

After we have changed the url of wordpress url, we have to redirect ?s=keyword to /model/keyword/ using 301. We can use some wordpress 301 redirection plugins to implement it or we process it in search.php.
