Ruby on Rails: Advanced search

Question

I\'m having trouble understanding the best way to make a advanced search form. I have had a good search on the internet, looking at some ways, but I can\'t get them to work,

Answer 1

I've been using MetaSearch in my application and found it quite convenient. If you've already considered it, what problems did you have?

There's also Ransack by the same author, it's a successor to MetaSearch.
