• Performing a fuzzy search may retrieve terms with similar spellings: su sach _ ((lang van) OR (dang van)) hoe. ((hieu va) or (lieu va)) cam xuc va hanh tai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach _ ((lang van) OR (dang van)) hoe. ((hieu va) OR (lieu va)) cam xuc va hanh tai cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach _ ((lang van) OR (dang van)) hoe. ((hieu va) or (lieu va)) cam xuc va hanh tai cua te".
• Adding a wildcard symbol may retrieve word variants: su sach _ ((lang van) OR (dang van)) hoe. ((hieu va) or (lieu va)) cam xuc va hanh tai cua te*.
