• If you are trying to use Boolean operators, they must be ALL CAPS: te sach nha lang van hoc. hieu van ((cau luc) OR (hau loc)) gia hanh vi ((cau treo) OR (cau tren)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach nha lang van hoc. hieu van ((cau luc) or (hau loc)) gia hanh vi ((cau treo) OR (cau tren))".
