• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach y) OR (sach 2)) nang x hoi. hieu ve cham soc va ((thanh hoi) OR (thanh hai)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach y) or (sach 2)) nang x hoi. hieu ve cham soc va ((thanh hoi) OR (thanh hai)) cua tre".
• Adding a wildcard symbol may retrieve word variants: te ((sach y) or (sach 2)) nang x hoi. hieu ve cham soc va ((thanh hoi) OR (thanh hai)) cua tre*.
