• Performing a fuzzy search may retrieve terms with similar spellings: tu sach thi ((hanh xa) or (hanh va)) hoi. ((hieu ve) OR (hieu va)) cam luc va hanh lam ha triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach thi ((hanh xa) OR (hanh va)) hoi. ((hieu ve) OR (hieu va)) cam luc va hanh lam ha triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach thi ((hanh xa) or (hanh va)) hoi. ((hieu ve) OR (hieu va)) cam luc va hanh lam ha triet".
