Indexing code below. Looks very simple. Is this correct?
IndexWriterConfig conf = new
IndexWriterConfig(Version.LUCENE_42, new
StandardAnalyzer(Version.LUCENE_42));
conf.setOpenMode(OpenMode.CREATE_OR_APPEND);
String indexPath = "<some-file-path>";
Directory dir=FSDirectory.open(new File(indexPath));
writer = new IndexWriter(dir,conf);
FieldType type = new FieldType();
type.setTokenized(true);
type.setIndexed(true);
type.setIndexOptions(IndexOptions.DOCS_AND_FREQS_AND_POSITIONS);
Field field = new Field("content", "one two two three", type);
luceneDoc.add(field);
writer.addDocument(luceneDoc);
writer.close();
Reading docFreq and totalTermFreq through terms-enum returns 0 and -1, for
all terms
