our best » your best, der best, hr best
yang jin » yang jie, yang jun, ying jin
jin kang » jin chang, jin kyung, jing fang

• If you are trying to use Boolean operators, they must be ALL CAPS: ((wing yan) OR (((dong sink) OR (dong ping)))) ya our best yang jin kang hai ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wing yan) or (((dong sink) OR (dong ping)))) ya our best yang jin kang hai ;*".
