Not kidding, but I thought about adding it there too! I didn't add it because I
got confused with the GenericAnalyzer. I thought it wouldn't work because it
didn't have an empty constructor (more especifically, thought it had something
like this [part of the
code|https://github.com/apache/jena/blob/a56f7710d88e368824042863e1ebef9afc7fd5f3/jena-text/src/main/java/org/apache/jena/query/text/assembler/GenericAnalyzerAssembler.java#L199]).
My mistake. Added a mention to the new filter under ConfigurableAnalyzer.

+1 ! And maybe it deserves now to have one or more entries under Tutorials as
well :-)
> SelectiveFoldingFilter for jena-text

> Key: JENA-1488
> URL: https://issues.apache.org/jira/browse/JENA-1488
> Project: Apache Jena
> Issue Type: Improvement
> Components: Text
> Affects Versions: Jena 3.6.0
> Reporter: Osma Suominen
> Assignee: Bruno P. Kinoshita
> Priority: Major
> Fix For: Jena 3.8.0
>
>
> Currently there's some support for accent folding in jena-text, because
> Lucene provides an ASCIIFoldingFilter. When this filter is enabled, a search
> for "deja vu" will match the literal "déjà vu" in the data.
> But we can't use it here at the National Library of Finland (for Finto.fi /
> Skosmos), because it folds too much! In the Finnish alphabet, in addition to
> the Latin a-z (which are in ASCII) we use the letters åäö and these should
> not be folded to ASCII. So we need a Lucene analyzer that can be configured
> with an exclude list, something like
>
> new SelectiveFoldingFilter(String excludeChars)
>
> and that can be also be configured via the Jena assembler just like other
> analyzers supported by jena-text.
>
> This was also briefly discussed on the skosmos-users mailing list:
> [https://groups.google.com/d/msg/skosmos-users/x3zR_uRBQT0/Q90-O_iDAQAJ]
> Apparently Norwegians have the same problem...
> I've discussed this with [~kinow] and he has some initial code to implement
> this feature, so I think we can turn this into a PR fairly soon.
