• Performing a fuzzy search may retrieve terms with similar spellings: tu ((sach lo) or (sach hoi)) nang xa hoi. ((hieu ve) OR (hieu va)) cua xuc va hanh doi cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach lo) OR (sach hoi)) nang xa hoi. ((hieu ve) OR (hieu va)) cua xuc va hanh doi cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach lo) or (sach hoi)) nang xa hoi. ((hieu ve) OR (hieu va)) cua xuc va hanh doi cua te*".
