spellcheck in dismax

[Ruixiang Zhang]

I put the following into dismax requestHandler, but no suggestion field is
returned.

    <lst name="defaults">
      <str name="spellcheck.onlyMorePopular">true</str>
      <str name="spellcheck.extendedResults">false</str>
      <str name="spellcheck.count">1</str>
    </lst>
    <arr name="last-components">
      <str>spellcheck</str>
    </arr>

But everything works if I put it as a separate requestHandler. Did I miss
something?

Thanks
Richard
