• If you are trying to use Boolean operators, they must be ALL CAPS: vu bach ty dung ha hoi. hieu van nam tuc va ((thanh vi) OR (thanh va)) ((cuu tre) OR (cua triet))~.
• Adding a wildcard symbol may retrieve word variants: vu bach ty dung ha hoi. hieu van nam tuc va ((thanh vi) or (thanh va)) ((cuu tre) or (cua triet))*.
