Hi Christian,
Thanks for your great work.

I'd like to ask you to modify the text_kr field type definition in schema.xml as follows
    <fieldType name="text_kr" class="solr.TextField" positionIncrementGap="100">
      <analyzer type="index">
        <tokenizer class="solr.KoreanTokenizerFactory"/>
        <filter class="solr.KoreanFilterFactory hasOrigin="true" hasCNoun="true"  bigrammable="true""/>
        <filter class="solr.LowerCaseFilterFactory"/>
        <filter class="solr.StopFilterFactory" ignoreCase="true" words="lang/stopwords_kr.txt"/>
      <analyzer type="query">
        <tokenizer class="solr.KoreanTokenizerFactory"/>
        <filter class="solr.KoreanFilterFactory hasOrigin="false" hasCNoun="false"  bigrammable="false""/>
        <filter class="solr.LowerCaseFilterFactory"/>
        <filter class="solr.StopFilterFactory" ignoreCase="true" words="lang/stopwords_kr.txt"/>

> Korean language has specific characteristic. When developing search service with lucene
& solr in korean, there are some problems in searching and indexing. The korean analyer
solved the problems with a korean morphological anlyzer. It consists of a korean morphological
analyzer, dictionaries, a korean tokenizer and a korean filter. The korean anlyzer is made
for lucene and solr. If you develop a search service with lucene in korean, It is the best
idea to choose the korean analyzer.
