• If you are trying to use Boolean operators, they must be ALL CAPS: ((toc sach) OR (((thuoc sach) OR (nuoc sach)))) ky dang ha hoi. thi van cac toc ta anh giao cua tu~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((toc sach) or (((thuoc sach) OR (nuoc sach)))) ky dang ha hoi. thi van cac toc ta anh giao cua tu~".
• Adding a wildcard symbol may retrieve word variants: ((toc sach) or (((thuoc sach) OR (nuoc sach)))) ky dang ha hoi. thi van cac toc ta anh giao cua tu*.
