Hi All,
I use the following field type definition of a Hungarian text field:
<fieldType name="text_hu" class="solr.TextField" positionIncrementGap="100"
uninvertible="false" omitTermFreqAndPositions="false">
<analyzer type="index">
<tokenizer name="standard"/>
<filter name="lowercase"/>
<filter name="snowballPorter" language="Hungarian"/>
<filter name="asciiFolding" preserveOriginal="true"/>
</analyzer>
<analyzer type="query">
<tokenizer name="standard"/>
<filter name="lowercase"/>
<filter name="snowballPorter" language="Hungarian"/>
</analyzer>
</fieldType>
Currently the core is empty. Solr is running as a service and I can access
the UI admin. As soon as I try to analyze how my title field works (which
has text_hu field type) I get the following error: *Error instantiating
stemmer for language Hungarianfrom class null.*
I have checked the documentation and it is stated that Hungarian is among
the supported language. I checked the details in the solr.log but I did not
get smarter:

Any idea, what is wrong here?
