• Performing a fuzzy search may retrieve terms with similar spellings: thu sach thu nang x hoi. ((hieu ve) OR (hieu va)) chat xuc va ((hanh vai) or (hanh tai)) cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach thu nang x hoi. ((hieu ve) OR (hieu va)) chat xuc va ((hanh vai) OR (hanh tai)) cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach thu nang x hoi. ((hieu ve) OR (hieu va)) chat xuc va ((hanh vai) or (hanh tai)) cua triet".
