DOCUMENT SIMILARITY APACHE LUCENE CODE
Even if your Analyzer allows stopwords, you might want to tell the MoreLikeThis code to ignore them, as for the purposes of document similarity it seems reasonable to assume that "a stop word is never interesting". Any word in this set is considered "uninteresting" and ignored. Set this to null for the field names to be determined at runtime from the IndexReader provided in the constructor. Sets the field names that will be used when generating the 'More Like This' query. The default field names that will be used is DEFAULT_FIELD_NAMES. Returns the field names that will be used when generating the 'More Like This' query. Words that appear in more than this many percent of all docs will be ignored. Set the maximum percentage in which words may still appear.
Generate "more like this" similarity queries.
