            "index_analyzer" : {                    
                "tokenizer" : "nGram",
                "filter" : ["lowercase"]
            },
            "search_analyzer" : {                                                    
                "tokenizer" : "nGram",
                "filter" : ["lowercase"]
            }
        },                               
        "// you'll need lucene dep for this: filter" : {                
            "snowball": {
                "type" : "snowball",
                "language" : "English"

wont it stem before indexing or i missed some thing in config ....

Answer 1

How looks your query?

your config does not look good. try:

 ...
"index_analyzer" : {                    
   "tokenizer" : "nGram",
   "filter" : ["lowercase", "snowball"]
},
 "search_analyzer" : {                                                    
    "tokenizer" : "nGram",
    "filter" : ["lowercase", "snowball"]
}
},
"filter" : {
                "snowball": {
                    "type" : "snowball",
                    "language" : "English"
                }
            }

I've had trouble overriding the "default_search" and "default_index" analyzer as well.

This works though. You can add "index_analyzer" to default all string fields with unspecified analyzers within a type, if need be.

curl -XDELETE localhost:9200/twitter

curl -XPOST localhost:9200/twitter -d '

  { "number_of_shards": 1,
    "analysis": {
       "filter": {
                "snowball": {
                    "type" : "snowball",
                    "language" : "English"
                }
                 },
       "analyzer": { "a2" : {
                    "type":"custom",
                    "tokenizer": "standard",
                    "filter": ["lowercase", "snowball"]
                    }
                  }
     }
  }
