• Performing a fuzzy search may retrieve terms with similar spellings: thuat lanh y tang ma hoi. hieu ((ve dao) or (de dao)) duc manh anh van ((cua tre) OR (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat lanh y tang ma hoi. hieu ((ve dao) OR (de dao)) duc manh anh van ((cua tre) OR (cua triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat lanh y tang ma hoi. hieu ((ve dao) or (de dao)) duc manh anh van ((cua tre) OR (cua triet))".
• Adding a wildcard symbol may retrieve word variants: thuat lanh y tang ma hoi. hieu ((ve dao) or (de dao)) duc manh anh van ((cua tre) OR (cua triet))*.
