Adrien Grand updated LUCENE-7536:
---------------------------------
Attachment: LUCENE-7536.patch
Here is a proposal: the multi-term component only emits the folded token, even
when {{preserveOriginal}} is true.
> ASCIIFoldingFilterFactory.getMultiTermComponent can emit two tokens
> -------------------------------------------------------------------

> Key: LUCENE-7536
> URL: https://issues.apache.org/jira/browse/LUCENE-7536
> Project: Lucene - Core
> Issue Type: Bug
> Reporter: Adrien Grand
> Priority: Minor
> Attachments: LUCENE-7536.patch
>
>
> My understanding is that it is a requirement for multi-term analysis to only
> normalize tokens, and not eg. remove tokens (stop filter) or add tokens (by
> tokenizing or adding synonyms). Yet
> ASCIIFoldingFilterFactory.getMultiTermComponent will return a factory that
> emits synonyms if preserveOriginal is set to true on the original filter.
> This looks like a bug to me but I'm not entirely sure how to fix it. Should
> the multi-term analysis component do ascii folding or not if the original
> factory has preserveOriginal set to true?
