An optional param name prefix of "tokenizerFactory." may be used for any init params that the SynonymFilterFactory needs to pass to the specified TokenizerFactory. If the TokenizerFactory expects an init parameters with the same name as an init param used by the SynonymFilterFactory, the prefix is mandatory.
The optional {@code format} parameter controls how the synonyms will be parsed: It supports the short names of {@code solr} for SolrSynonymParser and {@code wordnet} for and WordnetSynonymParser, or your own {@code SynonymMap.Parser} class name. The default is {@code solr}. A custom SynonymMap.Parser is expected to have a constructor taking:
boolean dedup - true if duplicates should be ignored, false otherwiseboolean expand - true if conflation groups should be expanded, false if they are one-directionalAnalyzer analyzer - an analyzer used for each raw synonym
