We are developing a cross-site publishing solution -- we've got it working for basic stuff and I have a good understanding of how to make it work using this tutorial among others.
We are now trying to create site lookup column and have that information come through the search crawl. I'm able to get site columns with managed metadata and other types, but the lookup column doesn't seem to come through. The other columns automatically generate both crawled and managed properties, but the lookup column only gets a crawled property.
We tried manually creating a managed property for the lookup and mapping the crawled property to it. But that doesn't seem to work either. Could that require a full crawl before it starts to work?
Anybody have experience bringing a site lookup column through cross-site publishing?
