• If you are trying to use Boolean operators, they must be ALL CAPS: tuyen tap ((tran chau) OR (tran huu)) đe co ban ve y tai ((cong dung) OR (cong luong)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tuyen tap ((tran chau) or (tran huu)) đe co ban ve y tai ((cong dung) OR (cong luong))".
• Adding a wildcard symbol may retrieve word variants: tuyen tap ((tran chau) or (tran huu)) đe co ban ve y tai ((cong dung) OR (cong luong))*.
