• Performing a fuzzy search may retrieve terms with similar spellings: thu cach thu sang ma hoi. hieu ve cam lo ((va hanh) OR (van hanh)) ((gia cua) or (bieu cua)) triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu cach thu sang ma hoi. hieu ve cam lo ((va hanh) OR (van hanh)) ((gia cua) OR (bieu cua)) triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu cach thu sang ma hoi. hieu ve cam lo ((va hanh) OR (van hanh)) ((gia cua) or (bieu cua)) triet*".
