Info

CJKWidthFilterFactory should be specified prior to this filter to normalize half-width katakana to full-width. Factory class: JapaneseKatakanaStemFilterFactory Arguments: minimumLength: terms below this length will not be stemmed. Default is 4, value must be 2 or more. CJK Width Filter Folds fullwidth ASCII variants into the equivalent Basic Latin forms, and folds halfwidth Katakana variants into their equivalent fullwidth forms. Factory class: CJKWidthFilterFactory (no arguments) Example: Hebrew, Lao, Myanmar, Khmer Lucene provides support, in addition to UAX#29 word break rules, for Hebrew's use of the double and single quote characters, and for segmenting Lao, Myanmar, and Khmer into syllables with the solr.ICUTokenizerF actory in the analysis-extras contrib module. To use this tokenizer, see solr/contrib/analysis-ext ras/README.txt for instructions on which jars you need to add to your solr_home/lib. See the ICUTokenizer for more information. Latvian Solr includes support for stemming Latvian, and Lucene includes an example stopword list. Factory class: solr.LatvianStemFilterFactory Arguments: None Example: Apache Solr Reference Guide 6.0 164
In: "tirgiem tirgus" Tokenizer to Filter: "tirgiem", "tirgus" Out: "tirg", "tirg" Norwegian Solr includes two classes for stemming Norwegian, NorwegianLightStemFilterFactory and NorwegianM inimalStemFilterFactory. Lucene includes an example stopword list. Another option is to use the Snowball Porter Stemmer with an argument of language="Norwegian". Also relevant are the Scandinavian normalization filters. Norwegian Light Stemmer The NorwegianLightStemFilterFactory requires a "two-pass" sort for the -dom and -het endings. This means that in the first pass the word "kristendom" is stemmed to "kristen", and then all the general rules apply so it will be further stemmed to "krist". The effect of this is that "kristen," "kristendom," "kristendommen," and "kristendommens" will all be stemmed to "krist." The second pass is to pick up -dom and -het endings. Consider this example: One pass Two passes Before After Before After forlegen forleg forlegen forleg forlegenhet forlegen forlegenhet forleg forlegenheten forlegen forlegenheten forleg forlegenhetens forlegen forlegenhetens forleg firkantet firkant firkantet firkant firkantethet firkantet firkantethet firkant firkantetheten firkantet firkantetheten firkant Factory class: solr.NorwegianLightStemFilterFactory Arguments: variant: Choose the Norwegian language variant to use. Valid values are: Example: nb: Bokmål (default) nn: Nynorsk no: both Apache Solr Reference Guide 6.0 165
