Creating a website with search filters like amazon and Ebay. Is it possible? I want to create a website which will be a search based. It will allow users to narrow down results based on categories and tags. The website is not a shopping website but will be a collection of articles. The user will narrow down the results using categories and sub categories and various types. I want to know that is this kind of functionality obtained from Drupal. I am using Joomla and its not allowing me to do what I want.
You can use something like Solr as that supports faceted searching.

It is rather complicated to set up though if you are using your own search server.
