I tried a search formula in xpages using a field name containing underscores, and I got syntax errors.
My search is very very easy
FIELD HR_FullName CONTAINS <value> or
FIELD HR_FullName CONTAINS Bryan
This says that query is not understandable. In fact, any field with an "_" in it gives query is not understandable. If I use a field without an underscore then it works.
I deleted the index and recreated it, but it still had this problem.
Am I going crazy or doing something wrong????
Yes the question was answered. The problem was that I had changed the definition of a field (or more than one) and the UNK table only lists one entry for field name, so when you try to do a search you can get this error. Knut added in a link to someone who had a similar issue.
The link had a way to rebuild the UNK table. My solution was just to replicate the db locally, delete the server version, and re replicate up. That fixed it.
