• If you are trying to use Boolean operators, they must be ALL CAPS: ((toc sac) OR (hoc sach)) ky dang mau hoa. thien van nam thuc va hanh ((vai cua) OR (hai cua)) tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((toc sac) OR (hoc sach)) ky dang mau hoa. thien van nam thuc va hanh ((vai cua) or (hai cua)) tre~".
• Adding a wildcard symbol may retrieve word variants: ((toc sac) OR (hoc sach)) ky dang mau hoa. thien van nam thuc va hanh ((vai cua) or (hai cua)) tre*.
