 You may optionally specify a starting location for the search to begin //start_expr//.  If the start is 1 or greater the search will begin from the specified character from the start.  If the start is < 0 then the search will begin from the nth character from the end.  The search will ALWAYS look forward. You may optionally specify a starting location for the search to begin //start_expr//.  If the start is 1 or greater the search will begin from the specified character from the start.  If the start is < 0 then the search will begin from the nth character from the end.  The search will ALWAYS look forward.
