Alexandre Rafalovitch commented on LUCENE-7687:
-----------------------------------------------
This reads to me as the underlying issue of whether ComplexPhrase query parser
uses underlying (automatically-constructed) MultiTerm analysis chain (and takes
into account multiterm-ready ascii folding filter) or does its own expansion
using pure tokens.
> ComplexPhraseQueryParser with AsciiFoldingFilterFactory (SOLR)
> --------------------------------------------------------------
>
> Key: LUCENE-7687
> URL: https://issues.apache.org/jira/browse/LUCENE-7687
> Project: Lucene - Core
> Issue Type: Bug
> Affects Versions: 6.4.1
> Environment: solr-6.4.1 (yes, solr, but I don't know where the bug
> exactly is)
> Reporter: Jochen Barth
>
> I modified generic *_txt-Field type to use AsciiFoldingFilterFactory on query
> & index.
> When quering with
> \{!complexphrase}text_txt:"König*" -- there are 0 results
> \{!complexphrase}text_txt:"Konig*" -- there are >0 results
> \{!complexphrase}text_txt:"König" -- there are >0 results (but less than the
> line above)
> and without \{!complexphrase} everything works o.k.
