• Performing a fuzzy search may retrieve terms with similar spellings: so ((sach ly) OR (sach lo)) lang ha hoi. lieu va lam truc va ((danh vi) or (dinh vi)) cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so ((sach ly) OR (sach lo)) lang ha hoi. lieu va lam truc va ((danh vi) OR (dinh vi)) cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so ((sach ly) OR (sach lo)) lang ha hoi. lieu va lam truc va ((danh vi) or (dinh vi)) cuu tre".
