• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) OR (te sach)) y lang xa hoi. lieu va ((dao tuc) or (cao suc)) va danh ban quan tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (te sach)) y lang xa hoi. lieu va ((dao tuc) OR (cao suc)) va danh ban quan tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (te sach)) y lang xa hoi. lieu va ((dao tuc) or (cao suc)) va danh ban quan tre".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) OR (te sach)) y lang xa hoi. lieu va ((dao tuc) or (cao suc)) va danh ban quan tre*.
