• If you are trying to use Boolean operators, they must be ALL CAPS: thu hai ky lang xa hoi. ((hieu van) OR (lieu va)) ((dau xua) OR (dao xuan)) va danh vi cuu tre.
• Adding a wildcard symbol may retrieve word variants: thu hai ky lang xa hoi. ((hieu van) or (lieu va)) ((dau xua) or (dao xuan)) va danh vi cuu tre*.
