CommonGramsFilter is useful for issuing phrase queries (i.e. "the cat") that contain stop words. Normally phrases contaning stop words would not match their intended target and instead, the query "the cat" would match all documents containing "cat", which can be undesirable behavior. Phrase query slop (eg, "the cat"~2) will not match any documents because common grams are indexed as shingled tokens that are adjacent to each other (i.e. the_cat is indexed as a single term). + + A customized common word list may be specified with the "words" attribute in the schema. + Optionally, the "ignoreCase" attribute may be used to ignore the case of tokens when comparing to the common words list. + + {{{ + <fieldtype name="testcommongrams" class="solr.TextField"> + <analyzer> + <tokenizer class="solr.LowerCaseTokenizerFactory"/> + <filter class="solr.CommonGramsFilterFactory" words="stopwords.txt" ignoreCase="true"/> + </analyzer> + </fieldtype> + }}} <<Anchor(KeepWordFilter)>> ==== solr.KeepWordFilterFactory ====
