dong yang » dong hoang, wang yang, yang yang
yang bell » jan bell, yang all
bell test » bell testing
law main » law pain, new main, law made

• If you are trying to use Boolean operators, they must be ALL CAPS: wang dong yang bell test ((((law main) OR (law making))) OR (kan min)) jeong hyeok ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang dong yang bell test ((((law main) OR (law making))) or (kan min)) jeong hyeok ;*".
