Match the search term exactly, but override for a tag

Hi,

In future version I will provide an option to customize exact match or partial match.

Now, For your requirement you can try these changes.
Go to this line https://github.com/5um17/wp-extended-search/blob/v2.1.2/includes/class-wpes-core.php#L381

And replace it with

$term = $wpdb->esc_like( $term ) . $n;

This will match the start of word with exact keyword but later part can vary.

Thanks
