There was a small issue with SharePoint 2010 that in advanced search could not find documents with specific string in custom column. We have a custom column Prof
In the list we can see that this field has that value and we can even filter on it.
So somthing is wrong with search?
Indeed if we search as ../_layouts/OSSSearchResults.aspx?k=(scope:"Documents") owsProf=QA
it finds ok the item. S the problem is ac tually in managed property. It is either does not exisit or not mapped correctly to crawled property. To fix that goto Central Admin, SEarch service administration - Metadata Property Mappings and add missing property - Prof - then map to crawled property ows_Prof(text)
