• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ly nang x hoi. hieu ((van hac) OR (van ha)) ((luc van) OR (luoc van)) khanh kiem chu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ly nang x hoi. hieu ((van hac) or (van ha)) ((luc van) OR (luoc van)) khanh kiem chu tre".
• Adding a wildcard symbol may retrieve word variants: te sach ly nang x hoi. hieu ((van hac) or (van ha)) ((luc van) OR (luoc van)) khanh kiem chu tre*.
