Although I haven’t directly experienced this limitation myself, I’ve just just read this thread and I do hope the Advanced Search Filters Addon is modified soon so the requisite code becomes standard.
It’s not satisfactory if the Advanced Search Filters imposes a requirement to search for Places – that should be an option, adjustable via the user-friendly back-end.
I trust it’s appropriate for me to add this to the ‘Requested Features’ list for this Add On?
