Searchlogic‘s goal is to keep your application free of searching clutter. It‘s is an ActiveRecord extension that allows you to perform simple and complex searches with a hash:

  @search = User.new_search(params[:search])
  @users = @search.all

These are just the basics of Searchlogic, it can do a lot more, including pagination, ordering data, etc.

sudo gem install searchlogic

For rails, as a gem (recommended)

  # config/environment.rb
  config.gem "searchlogic"

Or as a plugin (for older versions of rails)

  script/plugin install git://github.com/binarylogic/searchlogic.git

There are three storage options for files uploaded through attachment_fu:

• File system
• Database file
• Amazon S3
