title: Exception writing document id to the index; possible analysis error
body: <p>I am getting the above error while indexing the documents.</p>
  
  <pre><code>&lt;field name="a_suggest" type="my_suggest_field" indexed="true" stored="false"/&gt;
  &lt;field name="b_suggest" type="my_suggest_field" indexed="true" stored="false" /&gt;
  &lt;field name="c_suggest" type="my_suggest_field" indexed="true" stored="false"/&gt;
  
    &lt;fieldType name="my_suggest_field" class="solr.TextField" positionIncrementGap="100"&gt;
      &lt;analyzer type="index"&gt;
          &lt;tokenizer class="solr.WhitespaceTokenizerFactory"/&gt;
          &lt;filter class="solr.LowerCaseFilterFactory" /&gt;
          &lt;filter class="solr.EdgeNGramFilterFactory" maxGramSize="10" minGramSize="2"/&gt;
      &lt;/analyzer&gt;
      &lt;analyzer type="query"&gt;
          &lt;tokenizer class="solr.StandardTokenizerFactory" /&gt;
          &lt;filter class="solr.LowerCaseFilterFactory" /&gt;
      &lt;/analyzer&gt;
    &lt;/fieldType&gt;
  </code></pre>
  
  <p>And I am getting error when calling..</p>
  
  <pre><code>server.add(documents);
  </code></pre>
  
  <p>First of all, what is the meaning of <strong>Possible analysis error</strong>? Is it related to <code>my_suggest_field</code> index analyzer. Is it due to the order of the tokens, filters in the index analyzer?</p>
  
  <p>Thanks.</p>
