• Performing a fuzzy search may retrieve terms with similar spellings: te sach y ((nang xa) or (nang ma)) hoi. hieu qua cac xuc van ((thanh te) OR (thanh le)) cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y ((nang xa) OR (nang ma)) hoi. hieu qua cac xuc van ((thanh te) OR (thanh le)) cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y ((nang xa) or (nang ma)) hoi. hieu qua cac xuc van ((thanh te) OR (thanh le)) cua triet".
• Adding a wildcard symbol may retrieve word variants: te sach y ((nang xa) or (nang ma)) hoi. hieu qua cac xuc van ((thanh te) OR (thanh le)) cua triet*.
