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