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