Help with custom rewrite rules

I’m testing Geodirectory to know if it will be the right platform to migrate a big site using ACF, FacetWP and Frontend Publishing Pro

I need to adapt these URL structures to match the ones currently used:

1. /publish&listing_type=gd_place => /publish/listing

I tried:

add_rewrite_rule( 
    '^publish/listing/?$',
    'index.php?pagename=publish&listing_type=gd_place',
    'top'
);

But the parameter “listing_type=gd_place” is appended to the URL.

2. /publish&pid=33 => /listing/33/edit

I tried:

add_rewrite_rule( 
    '^listing/([0-9]+)/edit/?$',
    'index.php?pagename=publish&pid=$matches[1]',
    'top'
);

But the form is not filled and the title is “Add %%pt_single%%”.

I succeeded with this one: /index.php?post_type=gd_place&p=33&preview=true => /listing/33/preview

add_rewrite_rule( 
    '^listing/([0-9]+)/preview/?$',
    'index.php?post_type=gd_place&p=$matches[1]&preview=true',
    'top'
);

I don’t mind editing core files and disabling automatic updates for the moment.

PS: Is it possible to configure “Advanced Search Filters” addon to give priority to featured listings in the AJAX autocomplete functionality?

Thanks!
