Search for title and excerpt is broken with this plugin

[Zodiac1978]

A simplified Query for a standard search is this

SELECT SQL_CALC_FOUND_ROWS wp_posts.ID 
FROM wp_posts WHERE 1=1 
AND (((wp_posts.post_title LIKE '%wat%') 
OR (wp_posts.post_excerpt LIKE '%wat%') 
OR (wp_posts.post_content LIKE '%wat%')))

This plugin adds a new condition:

$where .= " AND REGEXP_REPLACE({$wpdb->posts}.post_content, '<.+?>', '') LIKE '%{$search_query}%'";

This breaks searching for title and excerpt.

We need to add the two OR statements again to fix this.

As an alternative, we need to change the third condition to our version of it.
