推荐答案

您是否要从索引中提取所有术语?

Are you looking extract all terms from the index?

private void GetIndexTerms(string indexFolder)
{
    List<String> termlist = new ArrayList<String>();
    IndexReader reader = IndexReader.open(indexFolder);
    TermEnum terms = reader.terms();
    while (terms.next()) 
    {
      Term term = terms.term();
      String termText = term.text();
      int frequency = reader.docFreq(term);
      termlist.add(termText);
    }
    reader.close();
}
