• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach 2) OR (sach y)) nang xa hoi. hieu co cham soc va danh ((kien cua) OR (khien cua)) te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach 2) or (sach y)) nang xa hoi. hieu co cham soc va danh ((kien cua) OR (khien cua)) te".
