Question

I have a site with Drupal, apache solr and tomcat as host for apache solr. I edited the tomcat schema.xml to enable utf-8 support. And that enabled searches for utf-8 characters.

However the actual resultset works unexpectedly. When searching for content with utf-8 characters, apache solr returns content with the “equivalent” character as well.

Example
A search for lag (law) will return content with låg (low). Very different things in Swedish. Is this possible to config. And in that case, where?

OK thank you both!

Uncommenting the

<charFilter class="solr.MappingCharFilterFactory" mapping="mapping-ISOLatin1Accent.txt"/>

Uncommenting the line above in type=”index” och type=”query” did the trick.

note <!-- below

 <analyzer type="query">
    <!--
    <filter class="solr.ASCIIFoldingFilterFactory"/>
    <charFilter class="solr.MappingCharFilterFactory" mapping="mapping-ISOLatin1Accent.txt"/>
    -->
    <tokenizer class="solr.WhitespaceTokenizerFactory"/>
    <filter class="solr.SynonymFilterFactory" synonyms="synonyms.txt" ignoreCase="true" expand="true"/>
    <filter class="solr.StopFilterFactory"
            ignoreCase="true"
            words="stopwords.txt"
            enablePositionIncrements="true"
            />
    <filter class="solr.WordDelimiterFilterFactory"
            protected="protwords.txt"
            generateWordParts="1"
            generateNumberParts="1"

    <filter class="solr.LowerCaseFilterFactory"/>
    <filter class="solr.SnowballPorterFilterFactory" language="English" protected="protwords.txt"/>
    <filter class="solr.RemoveDuplicatesTokenFilterFactory"/>
  </analyzer>
