recommendation Wordpress Search Filters

Guys/Gals and robots, I have been working on a WP website and looking for recommendation of a search query filter.
I have custom post and custom taxonomy. I have 2 pages where I need user to select/filter out searches using drop downs of the vocabulary’s of that taxonomy.

I have been using “Ultimate WP Query Search Filter” But its not working and not updated in years. page you can check out.
