• Performing a fuzzy search may retrieve terms with similar spellings: te sac ky lang ha hoi. hieu ((va tham) or (van tham)) duc ((va dan) OR (ca dan)) tai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sac ky lang ha hoi. hieu ((va tham) OR (van tham)) duc ((va dan) OR (ca dan)) tai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky lang ha hoi. hieu ((va tham) or (van tham)) duc ((va dan) OR (ca dan)) tai cua tre*".
