title: Solr Error when adding documents
body: <p>I've created a solr core called "fuzzy", however i'm unable to add documents to the core, I've tried adding the document using the following URL:</p>
  
  <pre><code>http://localhost:8983/solr/Fuzzy/update?stream.body=&lt;add&gt;&lt;doc&gt;&lt;field%20name="id"&gt;1&lt;/field&gt;&lt;field%20name="original"&gt;München&lt;/field&gt;&lt;field%20name="mutation"&gt;Munchen&lt;/field&gt;&lt;/doc&gt;&lt;/add&gt;&amp;commit=true
  </code></pre>
  
  <p>but i keep getting the messageL</p>
  
  <blockquote>
    <p>unknown UpdateRequestProcessorChain: add-unknown-fields-to-the-schema</p>
  </blockquote>
  
  <p>I'm not sure why i'm getting this message, In my config file I have :</p>
  
  <p><code>&lt;schemaFactory class="ClassicIndexSchemaFactory"/&gt;</code></p>
  
  <p>and schema.xml :</p>
