• Performing a fuzzy search may retrieve terms with similar spellings: su sach kho ((tang ma) OR (mang may)) hoa. hieu ve cam xuc va ((hanh vi) or (dinh ve)) cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach kho ((tang ma) OR (mang may)) hoa. hieu ve cam xuc va ((hanh vi) OR (dinh ve)) cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach kho ((tang ma) OR (mang may)) hoa. hieu ve cam xuc va ((hanh vi) or (dinh ve)) cua triet".
• Adding a wildcard symbol may retrieve word variants: su sach kho ((tang ma) OR (mang may)) hoa. hieu ve cam xuc va ((hanh vi) or (dinh ve)) cua triet*.
