I don’t have access to an EE2 MSM install to test myself, but have a question based on running into a problem on EE1.
Do site= and search:field= parameters work together now?
This was a limitation in EE1 (http://ellislab.com/forums/viewthread/68133/), but I see that the docs say “The site=”” parameter is available to the following: Channel Module: Every single tag.”
Thanks,
