• If you are trying to use Boolean operators, they must be ALL CAPS: ((toc sach) OR (doc sach)) o lang van hoe. hieu van pham chuc van tuan ((vi cua) OR (di cua)) tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((toc sach) OR (doc sach)) o lang van hoe. hieu van pham chuc van tuan ((vi cua) or (di cua)) tre~".
• Adding a wildcard symbol may retrieve word variants: ((toc sach) OR (doc sach)) o lang van hoe. hieu van pham chuc van tuan ((vi cua) or (di cua)) tre*.
