Hi,
For our Finnish audience we avoid folding some characters to alleviate
the problem. Along with MappingCharFilter this works pretty well. See
https://github.com/NatLibFi/finna-solr/blob/dev/vufind/biblio/conf/schema.xml#L7
for examples. Depending on your use case this could be a solution as
well. Note that the filter parameter hasn't always been there, so a
recent-enough Solr version is needed (I fail to recall the exact version).

Hi,
I'm looking at using ICUFoldingFilter for a customer, to fold e.g. Genéve to
Geneve and thus get better recall.
However, for some common Norwegian words, the folding makes them clash with
super-common words so it becomes impossible to find exactly what you want.
I imagined if ICUFoldingFilter had a preserverOriginal=true option, then it could leave
the original word in the index on the same position, and an exact match for
"Genéve" would score better than the normalized one. But this filter does not
support this.
Have anyone found a workaround for this, except from duplicating all content in
different fields with different analysis and search across them with different
weights?
