Unable to setup file based spell check

[Swapnadeep Mondal]

I am using the following configuration to implement file-based spell check
but it is not showing any suggestions.

{
        "name":"spellcheck",
        "class":"solr.SpellCheckComponent",
        "queryAnalyzerFieldType":"text_general",
        "spellchecker":{
          "name":"default",
          "classname":"solr.FileBasedSpellChecker",
          "sourceLocation":"/home/Downloads/words.txt"
          "spellcheckIndexDir":"./spellcheckerFile",
          "characterEncoding":"UTF-8",

"distanceMeasure":"org.apache.lucene.search.spell.LevenshteinDistance",
          "accuracy":"0.5"
}
What am I doing wrong? please help!
