• Performing a fuzzy search may retrieve terms with similar spellings: te ((sach v) OR (sach 2)) nang ma hoi. ((hieu va) or (lieu va)) nhan luc ban hanh vi cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach v) OR (sach 2)) nang ma hoi. ((hieu va) OR (lieu va)) nhan luc ban hanh vi cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach v) OR (sach 2)) nang ma hoi. ((hieu va) or (lieu va)) nhan luc ban hanh vi cua triet*".
