Running a spell check query using PHP

Let us configure Solr so that spell check happens on two fields, name and author:

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

2. Change the spellchecker field for the default spellchecker in solrconfig.xml to the new field we have just created. The default spellchecker uses the DirectSolrSpellChecker implementation of spell checker available with Solr.

   <lst name="spellchecker">
   <str name="name">default</str>
   <str name="field">spellfld</str>
