• Performing a fuzzy search may retrieve terms with similar spellings: ((te cac) OR (te cao)) ky lang ha hoi. hieu ve cac truc van ((hanh kem) or (hanh ve)) va triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((te cac) OR (te cao)) ky lang ha hoi. hieu ve cac truc van ((hanh kem) OR (hanh ve)) va triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te cac) OR (te cao)) ky lang ha hoi. hieu ve cac truc van ((hanh kem) or (hanh ve)) va triet".
