Handling wildcard search containing special characters (unicode)

this isn't the case, there's no unicode limitation here.

more likely, your analyzer is configured to lowercase text, so in the
index Kiinteistösihteeri is really kiinteistösihteeri
in other words, try kiinteistösih* and see how that works.

Following your suggestion, I tested with:
kiinteistösih*

but it doesn't show me the intended result.

I have found the reason why, this is because of the
ISOLatin1AccentFilterFactory filter which is present for both the
"index" and "query" analyzer.
Searching with:
kiinteistosih*
did the trick.

One question remains now: why should I lowercase terms containing a
wildcard and making the ISO Latin1 accent conversion myself while I do
have:
<analyzer type="query">
...
<filter class="solr.LowerCaseFilterFactory"/>
<filter class="solr.ISOLatin1AccentFilterFactory"/>
...
for the corresponding fieldType?
I would have guessed it would does it for me.

Your reply helped me a lot understanding what's going on.
Thank you very much for your participation!
