I'm looking for a search plugin that will allow me to add custom search filters based on tags or custom fields. It's a site for beer can collectors, so I would like to have the ability to add drop down selections to filter search results, For instance:
Size: (drop down would contain) 12 oz, 16 oz, 24 oz, etc.
Can Type: (drop down would contain) Flat Top, Cone Top, Cabottle
The closest thing I have found is the WP Custom Fields Search plugin, but it is no longer supported by the creator and no longer works with the new version of WP. Any suggestions would be greatly appreciated.
