• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ty) OR (sach y)) xang va hoc. lieu va hau xuc van thanh va ((cua viet) OR (hoa viet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ty) OR (sach y)) xang va hoc. lieu va hau xuc van thanh va ((cua viet) or (hoa viet))".
• Adding a wildcard symbol may retrieve word variants: te ((sach ty) OR (sach y)) xang va hoc. lieu va hau xuc van thanh va ((cua viet) or (hoa viet))*.
