Standard Filter
This filter removes dots from acronyms and the substring "'s" from the end of tokens. This filter depends on the
tokens being tagged with the appropriate term-type to recognize acronyms and words with apostrophes.
Factory class: solr.StandardFilterFactory
Arguments: None
This filter is no longer operational in Solr when the luceneMatchVersion (in solrconfig.xml) is
higher than "3.1".
Stop Filter
This filter discards, or stops analysis of, tokens that are on the given stop words list. A standard stop words list is
included in the Solr config directory, named stopwords.txt, which is appropriate for typical English language
text.
Factory class: solr.StopFilterFactory
Arguments:
words: (optional) The path to a file that contains a list of stop words, one per line. Blank lines and lines that
begin with "#" are ignored. This may be an absolute path, or path relative to the Solr config directory.
format: (optional) If the stopwords list has been formatted for Snowball, you can specify format="snowball"
so Solr can read the stopwords file.
ignoreCase: (true/false, default false) Ignore case when testing for stop words. If true, the stop list should
contain lowercase words.
