• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ly ((nang ma) OR (tang ma)) hoi. lieu va cham ((goc va) OR (loc va)) hanh di cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ly ((nang ma) OR (tang ma)) hoi. lieu va cham ((goc va) or (loc va)) hanh di cua tre".
• Adding a wildcard symbol may retrieve word variants: thu sach ly ((nang ma) OR (tang ma)) hoi. lieu va cham ((goc va) or (loc va)) hanh di cua tre*.
