This is my location Collection in mongodb:

{ "\_id" : ObjectId("5270d36f28f31fd8fa016441"), "stateName" : "A5", "cityName" : "ABCNEW2" }{ "\_id" : ObjectId("5270d37328f31fd8fa016442"), "stateName" : "A5", "cityName" : "ABC" }{ "\_id" : ObjectId("5270d37b28f31fd8fa016443"), "stateName" : "65", "cityName" : "ABCRW" }

I created one index using elastic Search:

POST /bwitter{"index":  
{ "number\_of\_shards": 1,  
"analysis": {  
"filter": {  
"mynGram" : {"type": "nGram", "min\_gram": 2, "max\_gram": 10}  
},  
"analyzer": { "a1" : {  
"type":"custom",  
"tokenizer": "standard",  
"filter": ["lowercase", "mynGram"]  
}  
}  
}  
}}

I created one mapping using elastic search:

PUT /bwitter/bweet/\_mapping{  
"bweet" : {  
"index\_analyzer" : "a1",  
"search\_analyzer" : "standard",  
"properties" : {  
"stateName": {"type":"string", "analyzer":"standard"},  
"cityName" : {"type" : "string" }  
}  
}

}

Created river as follows:

PUT /\_river/mongodb/\_meta{  
"type": "mongodb",  
"mongodb": {  
"db": "rakeshdb",  
"collection": "locations"  
},  
"index": {  
"name": "locations",  
"type": "bweet"  
}}

If, I query GET /locations/\_search?q=ABC, I get only one record (Full word  
search is happening, not happening for the partial word)

I almost spend a whole day on this but not able to solve this. Where am I  
going wrong?

I guess that it should be:  
PUT /\_river/mongodb/\_meta  
{  
"type": "mongodb",  
"mongodb": {  
"db": "rakeshdb",  
"collection": "locations"  
},  
"index": {  
"name": "bwitter",  
"type": "bweet"  
}  
}
