Hello!
Thank you for your reply.It is my oversight that I did not append the code at
(AnalyzeContext.java:124).
But when I try to use the StandardAnalyzer to do the same thing ,I met the same
Exception.
Here is my code(IndexWriter has already been initialized):
private static void indexFile(Index

Hi Carsten,
It doesn't sound as though an inverted index is really what you want to be
querying here, if I'm reading you right. You want to get the payloads for
spans at a specific position, but you don't particularly care about the actual
term at that position? You might find that BinaryDocV

Hi Alan,
thanks for the pointer, this is the right direction indeed. However,
these queries are based on a SpanQuery whic
There's the SpanPositionCheckQuery family - SpanRangeQuery, SpanFirstQuery,
etc. Is that the sort of thing you're looking for?

Hi,
Anybody is actively working on the classification package?
I was trying it with 4.2.1 and SimpleNaiveBayesClassifier seems to have a
bug - the local copy of BytesRef referenced by foundClass is affected by
subsequent TermsEnum.iterator.next() calls as the shared BytesRef.bytes
changes... I ca

hey there,
I think your english is perfectly fine! Given the info you provided
it's very hard to answer your question... I can't look into
org.wltea.analyzer.core.AnalyzeContext.fillBuffer(AnalyzeContext.java:124)
but apparently there is a nullpointer happening here. maybe you can
track that down
I am a lucene user from China,so my English is bad.I will try my best to
explain my problem.
The version I use is 4.2.I have a problem during I use lucene .
Here is my code:

NewsDao ndao = new NewsDao();

Actually, term vectors can store payloads now (LUCENE-1888), so if that
field was indexed with FieldType.setStoreTermVectorPayloads they should be
there.
But I suspect the TokenSources.getTokenStream API (which I think un-inverts
the term vectors to recreate the token stream = very slow?) wasn't f
TermVectors are per-document and do not contain payloads. You are reading the
per-document TermVectors which is a "small index" *stored* for each document as
a binary blob. This blob only contains the terms of this document with its
positions/offsets, but no payloads (offsets are used e.g. for h
Hi,
I'm trying to extract payloads from an index for specific tokens the
following way (inserting sample document number and term):
Terms terms = reader.getTermVector(16504, "term");
TokenStream tokenstream = TokenSources.getTokenStream(terms);
while (tokenstream.incrementToken()) {
