erlang a » lang a
min song » jin song, min hong, minh cong

• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang OR wan) OR lang) yan erlang a tests using min song jin ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang OR wan) or lang) yan erlang a tests using min song jin ;*".
