• Performing a fuzzy search may retrieve terms with similar spellings: su sach ((ty hang) or (thi cong)) x hoi. hieu va nam ((sua va) OR (vua va)) thanh linh cau treo~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ((ty hang) OR (thi cong)) x hoi. hieu va nam ((sua va) OR (vua va)) thanh linh cau treo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ((ty hang) or (thi cong)) x hoi. hieu va nam ((sua va) OR (vua va)) thanh linh cau treo".
• Adding a wildcard symbol may retrieve word variants: su sach ((ty hang) or (thi cong)) x hoi. hieu va nam ((sua va) OR (vua va)) thanh linh cau treo*.
