I was looking for an example to add direct generator to phrase suggester using elasticsearch java API. There are a lot of weired parameters when I'm creating DirecCandidateGenrator object. for example why should I give it a lucene IndexReader and how should I create it?

> DirectCandidateGenerator(DirectSpellChecker spellchecker, String field, SuggestMode suggestMode, IndexReader reader, double nonErrorLikelihood, int numCandidates)

> DirectCandidateGenerator(DirectSpellChecker spellchecker, String field, SuggestMode suggestMode, IndexReader reader, double nonErrorLikelihood, int numCandidates, Analyzer preFilter, Analyzer postFilter, Terms terms)
