• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ty ((nang xa) OR (nang cao)) hoi. thien van cam luc nha hang va ((cau tren) OR (dau tren)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ty ((nang xa) or (nang cao)) hoi. thien van cam luc nha hang va ((cau tren) OR (dau tren))".
