• If you are trying to use Boolean operators, they must be ALL CAPS: vu hai ky tang van hoi. hieu su cham ((xuc va) OR (loc va)) danh de ((cua triet) OR (cua viet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu hai ky tang van hoi. hieu su cham ((xuc va) or (loc va)) danh de ((cua triet) OR (cua viet))".
• Adding a wildcard symbol may retrieve word variants: vu hai ky tang van hoi. hieu su cham ((xuc va) or (loc va)) danh de ((cua triet) OR (cua viet))*.
