Multi Search Site

Does anybody know a good way to create a multi-search?

I’ve just had a phone interview with a company who have their website written in Joomla, and I’ve almost convinced them to use WordPress instead (because I don’t use Joomla). They have said they’d be interested if I could replicate their site.

This is the only part of the site I am unsure of.

The idea is that users could select from various drop-downs, such as Country, price, number of rooms, etc and then they could be given results on these selections. It is a real estate site.

Thanks
