In my test-system there is no problem searching for items within specific sites, using the site: tag. this looks like:
myTestSearch site:http://sharepoint.local/testsite/library1
The same webpart does have a problem with this keyword in the live-system on a different server. I don't get any results on that query. Same Data, Same Configuration, Full Crawling done, Same Settings in Managed Properties...
What could work here against me?
Thanks for any hint or answer!
