Configuring autocomplete and spellcheck 

The default solrconfig.xml does not include configuration for the Solr suggestor. To specify the autocomplete and spellcheck behavior, issue a query using the shards.qt= parameter

By default, the solrconfig.xml does not include configuration for the Solr suggestor. After configuring the search component in the solrconfig.xml for /suggest, you can issue a query specifying the autocomplete and spellcheck behavior using the shards.qt= parameter. For example, to test the suggestor:
$ curl "http://localhost:8983/solr/mykeyspace.mysolr/select?shards.qt=/suggest&qt=/suggest&q=testin"
