• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach thu lang van hoi. thi hanh cam ((luc va) OR (thuc va)) ((hanh hai) OR (nhanh hai)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach thu lang van hoi. thi hanh cam ((luc va) or (thuc va)) ((hanh hai) OR (nhanh hai)) cua tre".
