• If you are trying to use Boolean operators, they must be ALL CAPS: wang liang dan ii la ((sang min) OR (sang minh)) ((long shu) OR (long du)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang liang dan ii la ((sang min) OR (sang minh)) ((long shu) or (long du)) ;*".
