• Performing a fuzzy search may retrieve terms with similar spellings: vu sach lo ((nang xa) OR (lang xa)) hoi. ((hieu ve) or (hieu va)) cau trung va danh vi cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach lo ((nang xa) OR (lang xa)) hoi. ((hieu ve) OR (hieu va)) cau trung va danh vi cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach lo ((nang xa) OR (lang xa)) hoi. ((hieu ve) or (hieu va)) cau trung va danh vi cua triet*".
