Advanced search redirecting to another page then filter further

You should use manual sql queries to fetch the records as per your customized requirement and filters rather than the query function. Otherwise install a plugin that creates advanced search form with filters.

I am also sharing a reference link below which might be useful for you:

If none of it helps, do mention the output you are getting with your code.
