How to Refine Search Results

[eluser]Arun Kris[/eluser]
Hi All,

Iam having a web application in which after basic search the users should be able to filter the results he obtained using some filters.
For example let the user searched for a motor car. Then a list of motor cars will be displayed. Of these the user should be able to filter the cars based on certain criteria like color, place etc also the count of items under specific criteria should be displayed.

How can I implement this using code igniter
