`filepath`	A valid character string to the plaintext file containing the pattern.
`keyword`	A placeholder which signposts the beginning and end of the pattern to be extracted.
`preserve`	A boolean (`TRUE/FALSE`) value indicating whether or not keywords should be included in the extracted pattern (`TRUE`) or not (`FALSE`); default `FALSE`.
