• Performing a fuzzy search may retrieve terms with similar spellings: thuat sac ky mang da khoa. hieu ((ve cam) or (vu cham)) ((xuc va) OR (duc va)) dinh vai cua su~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat sac ky mang da khoa. hieu ((ve cam) OR (vu cham)) ((xuc va) OR (duc va)) dinh vai cua su*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat sac ky mang da khoa. hieu ((ve cam) or (vu cham)) ((xuc va) OR (duc va)) dinh vai cua su*".
