     * ``uppercase()``	-- returns the value of the field in upper case.
     * ``titlecase()``	-- returns the value of the field in title case.
     * ``capitalize()``	-- returns the value with the first letter upper case and the rest lower case.
-    * ``contains(pattern, text if match, text if not match)`` -- checks if the field's value is matched by the regular expression ``pattern``. Returns ``text if match`` if if the pattern matches the value, otherwise it returns ``text if no match``.
+    * ``contains(pattern, text if match, text if not match)`` -- checks if the field's value is matched by the regular expression ``pattern``. Returns ``text if match`` if the pattern matches the value, otherwise it returns ``text if no match``.
     * ``count(separator)`` -- interprets the value as a list of items separated by ``separator`` and returns the number of items in the list. Most lists use a comma as the separator, but ``authors`` uses an ampersand (&). Examples: ``{tags:count(,)}``, ``{authors:count(&)}``. Aliases: ``count()``, ``list_count()``
     * ``format_number(template)`` -- interprets the value as a number and formats that number using a Python formatting template such as ``"{0:5.2f}"`` or ``"{0:,d}"`` or ``"${0:5,.2f}"``. The formatting template must begin with ``{0:`` and end with ``}`` as in the above examples. Exception: you can leave off the leading "{0:" and trailing "}" if the format template contains only a format. See the template language and the `Python documentation <https://docs.python.org/3/library/string.html#formatstrings>`_ for more examples. Returns the empty string if formatting fails.
     * ``human_readable()`` -- expects the value to be a number and returns a string representing that number in KB, MB, GB, etc.
