• Performing a fuzzy search may retrieve terms with similar spellings: vu ((khach ky) or (hanh ky)) dang van hoi. hieu ve cau ((luc va) OR (tuc va)) dan va cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu ((khach ky) OR (hanh ky)) dang van hoi. hieu ve cau ((luc va) OR (tuc va)) dan va cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu ((khach ky) or (hanh ky)) dang van hoi. hieu ve cau ((luc va) OR (tuc va)) dan va cua tre".
• Adding a wildcard symbol may retrieve word variants: vu ((khach ky) or (hanh ky)) dang van hoi. hieu ve cau ((luc va) OR (tuc va)) dan va cua tre*.
