Perhaps you should try some spelling variations:
"while call becomes" » "while bill becomes", "while cap becomes", "while dallas becomes", "while cold becomes", "while cshall becomes", "while call comes", "while call incomes"
"while all become" » "while shall become", "while all come", "while all income", "while also become", "whilst all become", "while _ll become"
"while a times" » "while _ times", "while a time", "while a timed", "while a timer"

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (((("while call becomes") OR ("while all become"))) OR ("while a times"))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"while call becomes\") OR (\"while all become\"))) or (\"while a times\"))*".
• Removing quotes may allow a broader search: (((( while call becomes ) OR ( while all become ))) or ( while a times ))*.
