DM Smith commented on LUCENE-1350:
----------------------------------
Survey of other potential problem areas (I did not look at test cases):
o.a.l.index.memory.SynonymTokenFilter (generated synonyms do not propagate
payload or flags)
o.a.l.analysis.de.GermanStemFilter (creates a replacement token and does not
propagate payload or flags)
o.a.l.analysis.ngram.EdgeNGramTokenFilter (generated ngrams do not propagate
payload or flags; positionIncrement is inappropriate)
o.a.l.analysis.ngram.NGramTokenFilter (generated ngrams do not propagate
payload or flags; positionIncrement is inappropriate)
o.a.l.analysis.br.BrazilianStemFilter (creates a replacement token and does not
propagate payload or flags)
o.a.l.analysis.fr.ElisionFilter (creates a replacement token and does not
propagate payload or flags)
o.a.l.analysis.fr.FrenchStemFilter (creates a replacement token and does not
propagate payload or flags)
o.a.l.analysis.shingle.ShingleFilter (generated shingles do not propagate
payload or flags)
o.a.l.analysis.ru.RussianLowerCaseFilter (creates a replacement token and does
not propagate payload or flags)
o.a.l.analysis.ru.RussianStemFilter (creates a replacement token and does not
propagate payload or flags)
o.a.l.analysis.el.GreekLowerCaseFilter (creates a replacement token and does
not propagate payload or flags)
o.a.l.analysis.compound.CompoundWordTokenFilterBase (generated parts do not
propagate payload or flags)
o.a.l.analysis.th.ThaiWordFilter (creates a replacement for non-Thai words;
generated parts do not propagate payload or flags)
o.a.l.analysis.nl.DutchStemFilter (creates a replacement token and does not
propagate payload or flags)

> Key: LUCENE-1350
> URL: https://issues.apache.org/jira/browse/LUCENE-1350
> Project: Lucene - Java
> Issue Type: Bug
> Components: Analysis, contrib/*
> Reporter: Doron Cohen
> Assignee: Doron Cohen
> Attachments: LUCENE-1350.patch
>
>
> Passing tokens with payloads through SnowballFilter results in tokens with no
> payloads.
> A workaround for this is to apply stemming first and only then run whatever
> logic creates the payload, but this is not always convenient.
> Patch to follow that preserves the payload.
