• Performing a fuzzy search may retrieve terms with similar spellings: thu sach ty tang ha hoi. lieu va nay ((truc xa) OR (tuc xa)) hanh ((vi cua) or (di cua)) triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ty tang ha hoi. lieu va nay ((truc xa) OR (tuc xa)) hanh ((vi cua) OR (di cua)) triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ty tang ha hoi. lieu va nay ((truc xa) OR (tuc xa)) hanh ((vi cua) or (di cua)) triet".
• Adding a wildcard symbol may retrieve word variants: thu sach ty tang ha hoi. lieu va nay ((truc xa) OR (tuc xa)) hanh ((vi cua) or (di cua)) triet*.
