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