• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) or (su sach)) ((ky tang) OR (kho tang)) xa hoi. lieu va cam xuc va thanh vi luu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (su sach)) ((ky tang) OR (kho tang)) xa hoi. lieu va cam xuc va thanh vi luu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (su sach)) ((ky tang) OR (kho tang)) xa hoi. lieu va cam xuc va thanh vi luu tre".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) or (su sach)) ((ky tang) OR (kho tang)) xa hoi. lieu va cam xuc va thanh vi luu tre*.
