Michael McCandless updated LUCENE-3848: --------------------------------------- Attachment: LUCENE-3848-MockGraphTokenFilter.patch Patch, adding a MockGraphTokenFilter we can use to randomly insert fake graph arcs... > basetokenstreamtestcase should fail if tokenstream starts with posinc=0 > ----------------------------------------------------------------------- > > Key: LUCENE-3848 > URL: https://issues.apache.org/jira/browse/LUCENE-3848 > Project: Lucene - Java > Issue Type: Bug > Reporter: Robert Muir > Fix For: 3.6, 4.0 > > Attachments: LUCENE-3848-MockGraphTokenFilter.patch, LUCENE-3848.patch > > > This is meaningless for a tokenstream to start with posinc=0, > Its also caused problems and hairiness in the indexer (LUCENE-1255, > LUCENE-1542), > and it makes senseless tokenstreams. We should add a check and fix any that > do this. > Furthermore the same bug can exist in removing-filters if they have > enablePositionIncrements=false. > I think this option is useful: but it shouldnt mean 'allow broken > tokenstream', it just means we > don't add gaps. > If you remove tokens with enablePositionIncrements=false it should not cause > the TS to start with > positionincrement=0, and it shouldnt 'restructure' the tokenstream (e.g. > moving synonyms on top of a different word). > It should just not add any 'holes'. -- This message is automatically generated by JIRA.
