• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ty tang ma hoi. ((hieu van) OR (thien van)) ((chat xuc) or (cam xuc)) va dinh ve luu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty tang ma hoi. ((hieu van) OR (thien van)) ((chat xuc) OR (cam xuc)) va dinh ve luu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty tang ma hoi. ((hieu van) OR (thien van)) ((chat xuc) or (cam xuc)) va dinh ve luu tre".
• Adding a wildcard symbol may retrieve word variants: tu sach ty tang ma hoi. ((hieu van) OR (thien van)) ((chat xuc) or (cam xuc)) va dinh ve luu tre*.
