• Performing a fuzzy search may retrieve terms with similar spellings: su ((sach ky) or (sac ky)) nang xa hoi. ((hieu ha) OR (hieu hoa)) nam thuc dan thanh tai cuc triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sach ky) OR (sac ky)) nang xa hoi. ((hieu ha) OR (hieu hoa)) nam thuc dan thanh tai cuc triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sach ky) or (sac ky)) nang xa hoi. ((hieu ha) OR (hieu hoa)) nam thuc dan thanh tai cuc triet*".
