• Performing a fuzzy search may retrieve terms with similar spellings: thu sach ((thi hong) OR (thi cong)) ((ha hoi) or (ha noi)). thien van cam xuc va thanh nha cua viet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ((thi hong) OR (thi cong)) ((ha hoi) OR (ha noi)). thien van cam xuc va thanh nha cua viet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ((thi hong) OR (thi cong)) ((ha hoi) or (ha noi)). thien van cam xuc va thanh nha cua viet".
• Adding a wildcard symbol may retrieve word variants: thu sach ((thi hong) OR (thi cong)) ((ha hoi) or (ha noi)). thien van cam xuc va thanh nha cua viet*.
