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