Hunspell Stem Filter
The Hunspell Stem Filter provides support for several languages. You must provide the dictionary (.dic) and
rules (.aff) files for each language you wish to use with the Hunspell Stem Filter. You can download those
language files here. Be aware that your results will vary widely based on the quality of the provided dictionary
and rules files. For example, some languages have only a minimal word list with no morphological information.
On the other hand, for languages that have no stemmer but do have an extensive dictionary file, the Hunspell
stemmer may be a good choice.
Factory class: solr.HunspellStemFilterFactory
Arguments:
dictionary: (required) The path of a dictionary file.
affix: (required) The path of a rules file.
ignoreCase: (boolean) controls whether matching is case sensitive or not. The default is false.
strictAffixParsing: (boolean) controls whether the affix parsing is strict or not. If true, an error while
reading an affix rule causes a ParseException, otherwise is ignored. The default is true.
Example:
In: "jump jumping jumped"
Tokenizer to Filter: "jump", "jumping", "jumped"
Out: "jump", "jump", "jump"
Hyphenated Words Filter
This filter reconstructs hyphenated words that have been tokenized as two tokens because of a line break or
other intervening whitespace in the field test. If a token ends with a hyphen, it is joined with the following token
and the hyphen is discarded. Note that for this filter to work properly, the upstream tokenizer must not remove
trailing hyphen characters. This filter is generally only useful at index time.
