Super-duper Advanced Search?? (ie: multiple attribute criteria)

Hello,

Does Zen Cart offer an advanced search function that allows you to search for multiple criteria per attribute?

For example, let's say I have five different shirt colours red, green, white, black, blue - can a visitor search for RED OR GREEN OR WHITE shirt colours? From what I have seen of the advanced search function only one value can be selected, but it is very important to my store that visitors can search using various combinations of values.

Does nayone know if this is possible - does some module / add-on exist? The only store that does this that I have found so far is Magento, http://demo.magentocommerce.com/catalogsearch/advanced/ but it's a bit of a beast to install and I would rather use Zencart if possible...

From what I have seen of the advanced search function only one value can be selected, but it is very important to my store that visitors can search using various combinations of values.
There are default filters for category. etc.
Depending on how your products are entered - i.e. shirts in a shirt category - then searching for a colur in that category would net the correct result

Multiple terms can be entered - but you must have them in the product description

Thanks Kobra. But what I actually mean is that someone can choose to tick any number of values for a paritcular attribute, e.g. COLOUR has five options - green, black , red blue white and the visitor can tick green and black. This would bring back any shirts of colour green or colour black. I know I am being very specific in my requirements but it is very important for my website :-)

Tehy caan ent in the search terms box

green black

and select shirts from the categories

This gets it done - - If by "tick" you are seeking some check boxes - these would have to be dynamicically added as all products might not have color as a selecction and this would take a good bit of custom programming
