• Performing a fuzzy search may retrieve terms with similar spellings: ((so sach) OR (bo sach)) ty nang x hoi. lieu va cam tuc xa truong doi ((cuu tre) or (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((so sach) OR (bo sach)) ty nang x hoi. lieu va cam tuc xa truong doi ((cuu tre) OR (cua triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((so sach) OR (bo sach)) ty nang x hoi. lieu va cam tuc xa truong doi ((cuu tre) or (cua triet))".
• Adding a wildcard symbol may retrieve word variants: ((so sach) OR (bo sach)) ty nang x hoi. lieu va cam tuc xa truong doi ((cuu tre) or (cua triet))*.
