Robert Muir commented on LUCENE-3849: ------------------------------------- Thanks for bringing this back to life Mike. How did you deal with facets? Is this stuff out of date now that it no longer encodes with payloads? It was the big barrier to my previous patch: lots of tokenstreams never calling clearAtts at all (LUCENE-4318) If its no longer a problem, lets mark that issue resolved. Patch looks good to me, though it would be good to temporarily make end() final or something in TokenStream.java and review all tokenstreams that have an impl to make sure its ok. I still have my reservations about the posInc=0 stuff (i wish this was cleaner), but I don't see a better way: and this is really a bug we should fix. > position increments should be implemented by TokenStream.end() > -------------------------------------------------------------- > > Key: LUCENE-3849 > URL: https://issues.apache.org/jira/browse/LUCENE-3849 > Project: Lucene - Core > Issue Type: Bug > Affects Versions: 3.6, 4.0-ALPHA > Reporter: Robert Muir > Attachments: LUCENE-3849.patch, LUCENE-3849.patch, LUCENE-3849.patch, > LUCENE-3849.patch > > > if you have pages of a book as multivalued fields, with the default position > increment gap > of analyzer.java (0), phrase queries won't work across pages if one ends with > stopword(s). > This is because the 'trailing holes' are not taken into account in end().
