• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach tu nang xa hoi. ((hieu van) OR (hieu va)) cam ((xuc van) OR (luc van)) thanh hai chau treo*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach tu nang xa hoi. ((hieu van) OR (hieu va)) cam ((xuc van) or (luc van)) thanh hai chau treo*".
