• Performing a fuzzy search may retrieve terms with similar spellings: su sach tu quang xa hoi. thien ((van hac) OR (van hoc)) 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 quang xa hoi. thien ((van hac) OR (van hoc)) 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 quang xa hoi. thien ((van hac) OR (van hoc)) xuc va hanh ((vi cua) or (di cua)) tre*".
