• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ((y lang) OR (o lang)) van hoa. thi van cau xuc ban hanh ((vi cua) or (vai cua)) triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((y lang) OR (o lang)) van hoa. thi van cau xuc ban hanh ((vi cua) OR (vai cua)) triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((y lang) OR (o lang)) van hoa. thi van cau xuc ban hanh ((vi cua) or (vai cua)) triet".
• Adding a wildcard symbol may retrieve word variants: tu sach ((y lang) OR (o lang)) van hoa. thi van cau xuc ban hanh ((vi cua) or (vai cua)) triet*.
