• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu manh - anh ((tang va) OR (trang va)) dang cong dan ((toan tap) OR (toan ban)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu manh - anh ((tang va) or (trang va)) dang cong dan ((toan tap) OR (toan ban))".
