• Performing a fuzzy search may retrieve terms with similar spellings: ((phu san) or (thuy san)) kho tang ma noi. hieu va kham xuc ((van thanh) OR (ban thanh)) va cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((phu san) OR (thuy san)) kho tang ma noi. hieu va kham xuc ((van thanh) OR (ban thanh)) va cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((phu san) or (thuy san)) kho tang ma noi. hieu va kham xuc ((van thanh) OR (ban thanh)) va cua tre".
• Adding a wildcard symbol may retrieve word variants: ((phu san) or (thuy san)) kho tang ma noi. hieu va kham xuc ((van thanh) OR (ban thanh)) va cua tre*.
