• Performing a fuzzy search may retrieve terms with similar spellings: te sach thieu khang a hoi. ((hieu va) or (hieu qua)) cac thu van dich vu ((cuu tre) OR (cau tren))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach thieu khang a hoi. ((hieu va) OR (hieu qua)) cac thu van dich vu ((cuu tre) OR (cau tren))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach thieu khang a hoi. ((hieu va) or (hieu qua)) cac thu van dich vu ((cuu tre) OR (cau tren))*".
