  <p>I added a custom field in schema.xml which is inside
  solr-5.2.1\example\example-DIH\solr\solr\schema.xml</p>
  
  <p>should this field appear in schema browser in the web UI? Im also not getting it there.

  <pre><code>&lt;fieldType name="string_ci" class="solr.TextField"
          sortMissingLast="true" omitNorms="true"&gt;
          &lt;analyzer&gt;
              &lt;tokenizer class="solr.KeywordTokenizerFactory"/&gt;           
              &lt;filter class="solr.LowerCaseFilterFactory" /&gt;
          &lt;/analyzer&gt;
      &lt;/fieldType&gt;
