• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ty) OR (sach tu)) nang x hoi. lieu va cam ((duc va) OR (tuc va)) hanh vai cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ty) OR (sach tu)) nang x hoi. lieu va cam ((duc va) or (tuc va)) hanh vai cua te".
• Adding a wildcard symbol may retrieve word variants: te ((sach ty) OR (sach tu)) nang x hoi. lieu va cam ((duc va) or (tuc va)) hanh vai cua te*.
