• Performing a fuzzy search may retrieve terms with similar spellings: so ((sanh ky) or (nganh ky)) nang x hoi. ((hieu va) OR (lieu va)) co suc gia thanh va cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so ((sanh ky) OR (nganh ky)) nang x hoi. ((hieu va) OR (lieu va)) co suc gia thanh va cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so ((sanh ky) or (nganh ky)) nang x hoi. ((hieu va) OR (lieu va)) co suc gia thanh va cua te*".
