Question

is it possible to get the results using the suggested keyword by spell checker.
For example, when I search for whar, solr correctly suggests wharf, but is it possible to get the results for wharf in the same request?

Answer 1

you can define the Solr spellchecker settings in the request handler to get the spell suggestion with the response itself.

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

     <!-- Query settings -->
     <str name="defType">edismax</str>
     <str name="qf">
        text^0.5 features^1.0 name^1.2 sku^1.5 id^10.0 manu^1.1 cat^1.4
     </str>
     <str name="q.alt">*:*</str>
     <str name="rows">10</str>
     <str name="fl">*,score</str>

     <!-- Spell checking defaults -->
     <str name="spellcheck">on</str>
     <str name="spellcheck.collate">true</str>
     <str name="spellcheck.onlyMorePopular">false</str>
     <str name="spellcheck.extendedResults">false</str>
     <str name="spellcheck.count">3</str>
   </lst>

   <!-- append spellchecking to our list of components -->
   <arr name="last-components">
     <str>spellcheck</str>
   </arr>
</requestHandler>

The request handler can be used with the query with the qt param e.g. qt=custom_handler

EDIT –
Mistook the question.
This is not possible. you can’t get the results and for the spell suggestion in the same call. You would need to requery.
