• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sach) OR (toc sach)) ((v nang) OR (vu nang)) ma hoa. thien van thanh luc va hang hai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sach) or (toc sach)) ((v nang) OR (vu nang)) ma hoa. thien van thanh luc va hang hai cua tre~".
• Adding a wildcard symbol may retrieve word variants: ((te sach) or (toc sach)) ((v nang) OR (vu nang)) ma hoa. thien van thanh luc va hang hai cua tre*.
