If this could be fixed (i.e. indexing the _end_ of a span) I think all

That would be really nice. Full standoff annotations open a lot of doors.
If we had them, though, I'm not sure exactly which of Mike's methods you'd
use? I thought payloads were completely token-based and could not be
attached to spans regardless. And the SynonymFilter is really to mimic the

Can you provide some examples of terms that don't work and the index token

Make sure that the Analyzer you are using doesn't do any magic on the
indexed terms - your query term is unanalyzed. Maybe multiple, but distinct,
index terms are analyzing to the same, but unexpect

The index I'm testing with is German Wikipedia and I've been testing
with different (arbitrarily chosen) terms. I'm listing some results, the

I would like to be able to display up to multiple millions of lat/lng

Parts-of-speech is available now, in the indexer.
LUCENE-2899 adds OpenNLP to the Lucene&Solr codebase. It does
parts-of-speech, chunking and Named Entity Recognition. OpenNLP is an
Apache project for natural-language processing.
Some parts are in Solr that could be in Lucene.

It is not clear this is exactly what is needed/being discussed.

This adds it to a token, not a span. 'same position' does no
I should not have added that note. The Opennlp patch gives a concrete
example of adding an annotation to text.

Cool! Sounds great! :-)
Any pointers to a (Lucene) example that attaches a payload to a
start..end span that is more than one token?
thanks,

Hi Robert,
Our sysadmins installed a later java version (info below) and I redid the
merge and then ran CheckIndex both using Java7. Same error (appended

I suppose I could try merging 2 indexes, run checkindex and if its ok merge
3 indexes etc up to 12 to find the point where the proble
Hi Glen,
I don't believe you can attach a single payload to multiple tokens. What I did
for a similar requirement was to combine the tokens into a single "_" delimited
single token and attached the payload to it. For example:
