Highlighting simple.pre and simple.post values getting ignored

[Shamik Bandopadhyay]

Hi,

  I'm facing a weird issue where the specified "hl.simple.pre" and
"hl.simple.post" values for highlighting is getting ignored. In my test
handler, I've the following entry:

<!-- Highlighting defaults -->
<str name="hl">true</str>
<str name="hl.simple.pre"><![CDATA[<span class="vivbold qt0">]]></str>
<str name="hl.simple.post"><![CDATA[</span>]]></str>
<str name="hl.fl">name subject</str>
<str name="hl.encoder">html</str>
<str name="f.subject.hl.fragsize">200</str>
<str name="hl.usePhraseHighlighter">false</str>
<str name="hl.useFastVectorHighlighter">true</str>
<str name="hl.boundaryScanner">breakIterator</str>

          <str name="hl.bs.country">US</str>
        </lst>
      </boundaryScanner>
    </highlighting>
  </searchComponent>

As you can see, I've specified the simple.pre and simple.post values in the
request handler as well as under standard formatter.

But, search result is always wrapping the term with <em></em>, not sure
where is this value coming from. There's no reference of it in solrconfig
file. Looks like it's ignoring the value from solrconfig and defaulting it
to <em>.

Can someone provide any pointer ? I'm using Solr 4.7.

Thanks,
Shamik
