• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((ly nang) OR (ly vang)) xa hoi. hieu viec cua xuc va ((hanh di) OR (hang di)) cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((ly nang) or (ly vang)) xa hoi. hieu viec cua xuc va ((hanh di) OR (hang di)) cua te".
