• If you are trying to use Boolean operators, they must be ALL CAPS: ((so sach) OR (((toc sach) OR (thuoc sach)))) ky dang van hoi. lieu va cac tru va hang tai cuu tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((so sach) or (((toc sach) OR (thuoc sach)))) ky dang van hoi. lieu va cac tru va hang tai cuu tre~".
• Adding a wildcard symbol may retrieve word variants: ((so sach) or (((toc sach) OR (thuoc sach)))) ky dang van hoi. lieu va cac tru va hang tai cuu tre*.
