• If you are trying to use Boolean operators, they must be ALL CAPS: thu ((sach tu) OR (sach thu)) hanh xa hoi. ((hieu va) OR (lieu va)) cam duc va thanh tri cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu ((sach tu) OR (sach thu)) hanh xa hoi. ((hieu va) or (lieu va)) cam duc va thanh tri cua tre".
• Adding a wildcard symbol may retrieve word variants: thu ((sach tu) OR (sach thu)) hanh xa hoi. ((hieu va) or (lieu va)) cam duc va thanh tri cua tre*.
