• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach tu) OR (sach ty)) xang xa hoi. lieu va cam ((tuc va) OR (tuc xa)) thanh vi cua tu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach tu) or (sach ty)) xang xa hoi. lieu va cam ((tuc va) OR (tuc xa)) thanh vi cua tu".
