Perhaps you should try some spelling variations:
"pen name" » "pena name", "peon name", "penn name", "pen nace", "pen dame", "pen game"
"open name" » "opena name", "opeon name", "openn name", "open nace", "open dame", "open game"
"penna name" » "penana name", "peonna name", "pennna name", "penna nace", "penna dame", "penna game"
"penna same" » "penana same", "peonna same", "pennna same", "penna some", "penna sam"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("pen name") OR ("open name"))) OR ((("penna name") OR ("penna same"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"pen name\") OR (\"open name\"))) OR (((\"penna name\") OR (\"penna same\"))))".
• Removing quotes may allow a broader search: (((( pen name ) OR ( open name ))) OR ((( penna name ) OR ( penna same )))).
• Adding a wildcard symbol may retrieve word variants: (((("pen name") OR ("open name"))) OR ((("penna name") OR ("penna same"))))*.
