While the existing version of Solr in eZ Find supports solr.MappingCharFilterFactory , it is possibly an old version (see https://issues.apache.org/jira/browse/SOLR-822 ), and it doesn't support solr.CharStreamAwareWhitespaceTokenizerFactory which appears to be needed (see http://wiki.apache.org/solr/SchemaDesign?highlight=(MappingCharFilterFactory)#head-cbd09984c67526fbfde825739d72e9c37139f52c ).

I've tried using MappingCharFilterFactory to map characters, with no success.

Steps to reproduce

1. Edit ezfind/java/solr/conf/schema.xml and add the charFilter line below to both the "query" and "index" analyzers:

<fieldType name="text" class="solr.TextField" positionIncrementGap="100">
      <analyzer type="index">
        <charFilter class="solr.MappingCharFilterFactory" mapping="mapping-macrons.txt"/>

2. Create a file in the same directory called mapping-macrons and paste the following:

"ā" => a
"Ä€" => A
"Ä“" => e
"Ä’" => E
"Ä«" => i
"Ī" => I
"ō" => o
"Ō" => O
"Å«" => u
"Ū" => U

3. Put some of the Unicode chars in mapping-macrons.txt into an XML-block in a content object on your eZ Publish site e.g "Māori".

4. Re-start Solr & re-index your site using the --clean option

5. Search for the mapped equivalent, e.g "maori"
