Similar content

Hi, all the processes are related to the titles and slugs because there would be a very high load to the server when checking the contents of all posts in database.

Anyway it is possible making a custom wp filter to make an entire search to compare with all posts and avoid the publish if the search return a similar content.
You can use as:

add_filter('wpematico_allow_insertpost', 'wpematico_check_similars', 50, 2);
function wpematico_check_similars( $willinsert, $event, $args) {
        [COMPARE PROCESS HERE]
        [IF SIMILAR $willinsert = FALSE]

	return $willinsert;
}

It’s very simple, but If you are interested we can do it for you for a fee. Just refer to the website premium support.

cheers
