• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky lang ((ha hoi) OR (xa hoi)). ((hieu van) OR (hieu va)) cam xuc ban hang vi cau treo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky lang ((ha hoi) or (xa hoi)). ((hieu van) OR (hieu va)) cam xuc ban hang vi cau treo".
