• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky dang mat hoa. lieu va nam ((luc va) OR (loc va)) ((hanh vai) OR (hanh va)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky dang mat hoa. lieu va nam ((luc va) OR (loc va)) ((hanh vai) or (hanh va)) cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach ky dang mat hoa. lieu va nam ((luc va) OR (loc va)) ((hanh vai) or (hanh va)) cua tre*.
