Partial Word – Text and Number value (postcodes)

It just doesn’t work that way. You can always match a shorter search term to a longer word, but not the other way around, because Relevanssi isn’t allowed to skip letters in the search term.

But the solution is fortunately fairly simple: you just need to add the space there. Check the search term: if it looks like a postcode without a space, add the space.

However, if those are UK postcodes, figuring out what looks like a postcode is not an easy task – there’s a rather wild variety of possibilities there.

But once you figure out how to recognise a postcode, you can do the adjustment with a filter:

add_filter( 'relevanssi_modify_wp_query', 'rlv_postcode_check' );
function rlv_postcode_check( $query ) {
    if ( $query->query_vars['s'] is a post code ) {
        $query->query_vars['s'] = the post code with the space
    }
    return $query;
}
