Hi Cédric,
thanks for your answer here and in JIRA.
Out of curiosity, does that mean that the comparator works on values
from the underlying database, and not from Lucene index?
For anybody interested and reading here, I opened
https://issues.apache.org/jira/browse/JCR-3522 for porting of a
NORMALIZE() function to SQL2.
Regards,
Jörg

Hi Jörg,
Your approach won't work with the current implementation as the order
clauses are not "analyzed", so changing the analyzer won't have any
effect.
It should be possible to add a NORMALIZE() function also in the
SQL/SQL2 grammar, reusing the NormalizeSortComparator introduced by
JCR-3443

Cédric

Hi,
we've got the problem that our SQL2 queries with ORDER BY clauses on
Strings do sort the Germans Umlauts at the end of the results, while
Umlauts should be sorted like their equivalent characters without the
accent (e.g. "ö" = "o").
According to https://issues.apache.org/jira/browse/JCR-3443, with
Jackrabbit 2.5.3 it should be possible to have a normalize() function
in XPath queries, but not in SQL2.
We're now thinking of modifying the Jackrabbit configuration, and in
particular setting the "analyzer" param to the SearchIndex with a
custom subclass of
org.apache.lucene.analysis.standard.StandardAnalyzer, which makes use
of a
https://lucene.apache.org/core/old_versioned_docs/versions/3_0_3/api/core/org/apache/lucene/analysis/ASCIIFoldingFilter.html
.
Does anybody per chance have an opinion whether that could be a
viable approach?
Thanks for answers + regards,
Jörg
