Advanced Search: taxomony1 + taxonomy2

I did not notice WPMU Dev having any advance search plug ins. Perhaps that is because there are some out there that I have not found.

I am excited to use Classifieds. I have create several taxonomies for example:

Taxonomy1 = locatons
1.1 = Austin
1.2 = Dallas
1.3 = Housotn

Taxonomy2= service
2.1 = housing
2.2 = treatment
2.3 = coaching

Taxonomy3=payments
3.1 = insurance
3.2. = self pay
3.3 = social security

I would like users to be able to search for Austin + housing + self pay

Any suggestions or plans to develop an advanced search?

Thank you -- Jason
