• Performing a fuzzy search may retrieve terms with similar spellings: te sach ty ((dang xay) OR (dang van)) hoi. hieu ve cam ((quoc gia) or (luoc gia)) thanh vi cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty ((dang xay) OR (dang van)) hoi. hieu ve cam ((quoc gia) OR (luoc gia)) thanh vi cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty ((dang xay) OR (dang van)) hoi. hieu ve cam ((quoc gia) or (luoc gia)) thanh vi cuu tre".
• Adding a wildcard symbol may retrieve word variants: te sach ty ((dang xay) OR (dang van)) hoi. hieu ve cam ((quoc gia) or (luoc gia)) thanh vi cuu tre*.
