----------------------------------

             Summary: Config API does not work when adding a component with DirectSolrSpellChecker
                 Key: SOLR-9154
                 URL: https://issues.apache.org/jira/browse/SOLR-9154
             Project: Solr
          Issue Type: Bug
          Components: config-api, spellchecker
            Reporter: Anshum Gupta


When trying to add a DirectSolrSpellchecker using the Config API (JSON), there seems to be a loss of information w.r.t the param types. The accuracy field, only in this specific case needs to be defined as a float it seems. While this is possible when updating the solrconfig,xml directly, the field type (float) can not be specified using JSON. 

Here are the steps to reproduce this issue:

{code}
#Bootstrapping
bin/solr start -c
bin/solr create -c foo
bin/post -c foo example/exampledocs/books.csv

#Add spell checker - This would hang and the logs contain recurring exceptions as mentioned below
curl http://localhost:8983/solr/foo/config -H 'Content-type:application/json' -d '{"update-searchcomponent": {"name":"spellcheck",       "class":"solr.SpellCheckComponent",       "spellchecker":[         { "name":"text_index_dictionary", "field":"text", "classname":"solr.DirectSolrSpellChecker", "distanceMeasure":"org.apache.lucene.search.spell.LevensteinDistance", "accuracy":0.5, "maxEdits":2, "minPrefix":1, "maxInspections":5, "minQueryLength":4, "maxQueryFrequency":0.001, "thresholdTokenFrequency":0.01}]}}'
{code}
