Solr 5.2.1 highlighting results are not available

[Michał Oleś]

I installed solr 5.2.1 and use dih example with tika integration to search
for pdf content. Everything work as expected except highlighting plugin.
When I execute the query I don't even see highlighting section in results:

  "responseHeader": {
    "status": 0,
    "QTime": 1,
    "params": {
      "indent": "true",

      "hl.simple.pre": "<em>",
      "hl.simple.post": "</em>",
      "hl.fl": "text",
      "wt": "json",
      "hl": "true"
    }
  },

  }
}

My solrconfig.xml is default from that example. I tried to add default
values but it won't changed anything:

 <requestHandler name="/browse" class="solr.SearchHandler">
    <lst name="defaults">
      <str name="echoParams">explicit</str>

      <!-- VelocityResponseWriter settings -->
      <str name="wt">velocity</str>
      <str name="v.template">browse</str>
      <str name="v.layout">layout</str>

      <!-- Query settings -->
      <str name="defType">edismax</str>
      <str name="q.alt">*:*</str>
      <str name="rows">10</str>
      <str name="fl">*,score</str>

      <!-- Faceting defaults -->
      <str name="facet">on</str>
      <str name="facet.mincount">1</str>

      <!-- Highlighting defaults -->
       <str name="hl">on</str>
       <str name="hl.fl">text</str>
       <str name="hl.preserveMulti">true</str>
      <str name="hl.encoder">html</str>
       <str name="hl.simple.pre">&lt;b&gt;</str>
       <str name="hl.simple.post">&lt;/b&gt;</str>
       <str name="f.text.hl.snippets">3</str>
       <str name="f.text.hl.fragsize">200</str>
       <str name="f.text.hl.alternateField">text</str>
       <str name="f.text.hl.maxAlternateFieldLength">750</str>
    </lst>
  </requestHandler>

Here is part of schema.xml:

<field name="text" type="text_general" indexed="false" stored="true"
multiValued="true"/>
<field name="text_index" type="text_general" indexed="true"
stored="false" multiValued="true"/>
<copyField source="text" dest="text_index"/>

As in example I use two fields (one for indexing and one for store value).
When I run debug I found that highlight plugin time = 0. So it looks like
this plugin isn't even got invoked. Also in solr admin panel under tab
"Plugins/Stats" for all org.apache.solr.highlight.* classes I got 0 request.
