Multicriteria search with several dropdown menu

Hi everyone,

Please I am looking for a plugin (or developing something with custom post type) (or tags) to perform a multicriteria search of posts.

In fact, I have a lot of products with their own features in three categories eg:

Fluid : water, oil, steam

Speed : low, medium, high

Pressure : low, medium, high, very high

People connecting to the web site could select with thick boxes or

dropdown menu the feature in each category, and with a submit button, get the list with their link of all products with right criteria.

Any suggestion?

Thanks, JeanLuc
