• Performing a fuzzy search may retrieve terms with similar spellings: te sach thu ((nang ma) OR (nang cao)) hoi. hieu ve cam xuc va thanh lai ((dua tren) or (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach thu ((nang ma) OR (nang cao)) hoi. hieu ve cam xuc va thanh lai ((dua tren) OR (cuu tre)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach thu ((nang ma) OR (nang cao)) hoi. hieu ve cam xuc va thanh lai ((dua tren) or (cuu tre))".
• Adding a wildcard symbol may retrieve word variants: te sach thu ((nang ma) OR (nang cao)) hoi. hieu ve cam xuc va thanh lai ((dua tren) or (cuu tre))*.
