• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach v) OR (sach va)) nang x hoi. hieu qua tham soc va danh ((dien cuu) OR (dien cua)) tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach v) or (sach va)) nang x hoi. hieu qua tham soc va danh ((dien cuu) OR (dien cua)) tre*".
