Error loading class 'solr.ASCIIFoldingFilterFactory'

[Sethi, Parampreet]

Hi All,

I am using solr 1.3. I get the below mentioned error when included the 
solr.ASCIIFoldingFilterFactory on 'text' field while index and query time:

SEVERE: org.apache.solr.common.SolrException: Error loading class 
'solr.ASCIIFoldingFilterFactory'

          ...

My schema.xml looks like:

<fieldtype name="text" class="solr.TextField" positionIncrementGap="100">
      <analyzer type="index">
        <tokenizer class="solr.WhitespaceTokenizerFactory"/>

        <filter class="solr.RemoveDuplicatesTokenFilterFactory"/>
        <filter class="solr.ASCIIFoldingFilterFactory"/>
      </analyzer>
    </fieldtype>

Any pointers how this issue can be fixed will be great.

Thanks!
