You do not need to filter anything manual, just use a while-loop: IndexReader reader = ... TermEnum tenum = new PrefixTermEnum(reader, new Term(field, prefix)); do { if (tenum.term() == null) break; final String termText = tenum.term().text(); ... // do something with the listed term } while (tenum.next()); About your question: Depending on the used analyzers you may find the terms in modified form (lowercased, stemmed,...).
