Hi soren,
Thanks a lot for help.
As you suggest me, i written the code, but i wonder Field does not contain
Store, Index YES etc. It only contains Field.Keyword, Field.Text etc. Am i
missing something. My Code is as Below.
indexWriter = new IndexWriter(indexpath, analyzer, false);
// Create document
Document doc = new Document();
doc.add(Field.Keyword(URI_FIELD, uri.toString()));
doc.add(Field.Text(CONTENT_TEXT, readContent(revisionDescriptor,
revisionContent)));
//It gives error
/* doc.add(new Field("frequency", "field value", Field.Store.YES,
Field.Index.TOKENIZED, Field.TermVector.YES));*/
if ( revisionContent != null && revisionDescriptor != null ) {
List extractor =
ExtractorManager.getInstance().getContentExtractors(uri.getNamespace().getName(),
(NodeRevisionDescriptors)null, revisionDescriptor);
for ( int i = 0, l = extractor.size(); i < l; i++ ) {
Reader reader =
((ContentExtractor)extractor.get(i)).extract(new
ByteArrayInputStream(revisionContent.getContentBytes()));
doc.add(Field.Text(CONTENT_TEXT, reader));
}
}
indexWriter.addDocument(doc);
indexWriter.optimize();

Hello Aslam,
you should store the TermVector in the index as well:
doc.add(new Field("field name", "field value", Field.Store.YES,
Field.Index.TOKENIZED, Field.TermVector.YES));
"A term vector is a list of the document's terms and their number of
occurences in that document."
The IndexReader allows you to access the TermVector of a document:
TermFreqVector IndexReader.getTermFreqVector(int docNumber, String field)
I hope it helps.
Sören
