dong sink » dong sin, dong bin, dong ping
ya bhutan » _ bhutan, 16 bhutan
zhang zhi » zhong zhi, zhang wei, zhang dai

• If you are trying to use Boolean operators, they must be ALL CAPS: ((dong nan) OR (dong sink)) ya bhutan gender das meer ((zhang zhi) OR (wang zhi)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong nan) or (dong sink)) ya bhutan gender das meer ((zhang zhi) OR (wang zhi)) ;*".
