• If you are trying to use Boolean operators, they must be ALL CAPS: toc sach tu lang xa hoi. thien van nam ((thuc va) OR (thuc dan)) ((hang di) OR (hang doi)) cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sach tu lang xa hoi. thien van nam ((thuc va) or (thuc dan)) ((hang di) OR (hang doi)) cua te".
