1. The entered string does not show in the selection box ... in beta it was at the bottom.
2. The results are clearly incorrect
1. This will be fixed in the next 6.0a Beta.
2. Is your library index missing? Can you get results for "unmeaning" in a Basic Search (in this, or any, resource)?
U wasn't indexing then but I am now. Even while indexing a standard search panel finds hits.
Fixed in 6.0a Beta 2.
