Filter Plugin for Search Results

Hi,

I would like to know a good filter plugin that can be implemented on the search results and listing page where users can filter businesses are per their requirement. I did come across FacetWP plugin, does it work with multisite, post indexer and global site search.

Also please suggest if there is an alternative free and paid tool if this is not the right plugin for this setup.

Thanks and Regards,
