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