All attributes are optional:
ignoreCase defaults to falsewords should be the name of a stopwords file to parse, if not
specified the factory will use EnglishAnalyzer.ENGLISH_STOP_WORDS_SET
format defines how the words file will be parsed,
and defaults to wordset. If words is not specified,
then format must not be specified.
The valid values for the format option are:
wordset - This is the default format, which supports one word per
line (including any intra-word whitespace) and allows whole line comments
beginning with the "#" character. Blank lines are ignored. See
WordlistLoader.getLines for details.
snowball - This format allows for multiple words specified on each
line, and trailing comments may be specified using the vertical line ("|").
Blank lines are ignored. See
WordlistLoader.getSnowballWordSet
for details.
