• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y ((nang xa) OR (nang ma)) hoi. hieu va cam ((xuc va) OR (tuc va)) thanh doi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y ((nang xa) or (nang ma)) hoi. hieu va cam ((xuc va) OR (tuc va)) thanh doi cua te".
• Adding a wildcard symbol may retrieve word variants: te sach y ((nang xa) or (nang ma)) hoi. hieu va cam ((xuc va) OR (tuc va)) thanh doi cua te*.
