Improve security of AJAX customer search callback function LIKE query

[arraypress]

Bug Report

Expected behavior

This isn't a bug per-say, but something I noticed that could be improved in the code base. For database search/like queries, it's better to use this syntax:

$search =  sanitize_text_field( $_GET['s'] );
$search_like = '%' . $wpdb->esc_like( $search ) . '%';

Instead of the current way:

$search = esc_sql( sanitize_text_field( $_GET['s'] ) );
