Changing python regex method from match to search

[ewolinetz]

Changing due to variable content structure
new_file_contents is structured in such a way that we need to search anywhere in the string.

>>> for curr_line in current_contents.split("\n"):
...     print curr_line
... 
index: 
  number_of_shards: 2
  number_of_replicas: 1
bogusness: true

>>> for line in white_list:
...     regex_line = r".+" + re.escape(line) + r":.*\n"
...     new_line_file = re.match(regex_line, current_contents)
...     if new_line_file:
...         print new_line_file.group(0)
...     else:
...         print ""
... 




>>> for line in white_list:
...     regex_line = r".*" + re.escape(line) + r":.*\n"
...     new_line_file = re.search(regex_line, current_contents)
...     if new_line_file:
...         print new_line_file.group(0)
...     else:
...         print ""
... 
  number_of_shards: 2

  number_of_replicas: 1
