search in a multisite installation

Hello everybody!

I hve an installation like this:

www.domain.com (main site)
www.domain.com/site A
www.domain.com/site b

Sites uses the same db except for site a & b that uses differents prefixes for cache-blocks-variable and menu tables.

Nodes are virtually separated by taxonomy (site A, site B) this way i can implement views that shows selected nodes (a subset for site A and a subset for site B)

When I use the search module from one of the sites it returns informations about all the nodes (that's what i want) but when I click on a result it doesn't redirect to the right site, for example I search from siteA and one of the result "virtually" belongs to site B, click on it but themes, blocks and menus are always from site A not B.

Is there a way to tell search module to build the right link?

Thank you
