StackOverflow ... the errors, not the site

[Lajos]

All,

Just playing around with the SuggestComponent, trying to compare results 
with the old-style spell-check-based suggester. Tried this config 
against a string field:

  <requestHandler name="/suggest2" class="solr.SearchHandler">
     <lst name="defaults">
       <str name="wt">json</str>
       <str name="indent">true</str>
       <str name="suggest">true</str>
       <str name="suggest.count">10</str>
       <str name="suggest.dictionary">default</str>
     </lst>
     <arr name="components">
       <str>suggest2</str>
     </arr>
  </requestHandler>

  <searchComponent name="suggest2" class="solr.SuggestComponent">
        <lst name="suggester">
      <str name="name">default</str>
      <str name="lookupImpl">FuzzyLookupFactory</str>
      <str name="dictionaryImpl">DocumentDictionaryFactory</str>
      <str name="field">title</str>
      <str name="weightField">price</str>
      <str name="suggestAnalyzerFieldType">string</str>
    </lst>
  </searchComponent>

I hit this URL:

/suggest2?q=ab&suggest.build=true

and that works, but because "title" was as StrField, it wasn't quite 
what I wanted.

So I tried a TextField, "description". And I get this, with the same URL:

Thanks,
