I'm working on a search feature that when typing something make an ajax call to get the results. I wanna caches the search action with search keywords in memory_cache, so i make it like this: 

# caches_action with GET parameters

caches_action :search_posts, :cache_path => Proc.new { |c| c.params }

My question is how can i expire the action with parameters too? Is there another way to make my feature works?

You have several options to expire this kind of cache.

First one (simpler one) is to add :expires_in option to your caches_action statement - for example:

caches_action :search_posts, :cache_path => Proc.new { |c| c.params }, :expires_in => 16.hours.to_i

This will automatically expire this key after some time.

Or you can expire this cache using expire_action method from controller. It should be like:

expire_action :action => 'posts', :q => 'query'

given you have requested this page with one parameter q=query .

You can read more in the official documentation .
