I'm beasting 1000 iterations of TestRandomChains with the patch, and run 110
found the following reproducing seed - maybe it's ShingleFilter's fault? (I
didn't investigate further):

> Track PositionLengthAttribute abuse
> -----------------------------------
>
> Key: LUCENE-7708
> URL: https://issues.apache.org/jira/browse/LUCENE-7708
> Project: Lucene - Core
> Issue Type: Bug
> Components: core/queryparser, modules/analysis
> Reporter: Jim Ferenczi
> Attachments: LUCENE-7708.patch, LUCENE-7708.patch
>
>
> Some token filters uses the position length attribute of the token stream to
> encode the number of terms they put in a single token.
> This breaks the query parsing because it creates disconnected graph.
> I've tracked down the abusive case to 2 candidates:
> * ShingleFilter which sets the position length attribute to the length of the
> shingle.
> * CJKBigramFilter which always sets the position length attribute to 2.
> I don't think these filters should set the position length at all so the best
> would be to remove the attribute from these token filters but this could
> break BWC.
> Though this is a serious bug since shingles and cjk bigram now produce
> invalid queries.
