Java getSource map data issue and search queries

Elastic Stack Elasticsearch
1

Hello Experts,

I am a newbie to Elastic Search and I am using elastic search to support my RESTful webservices.
Here is how I am indexing my JSON documents

PUT users/group/1312
{
"userID" : "U1234",
"groupName": "G2",
"groupID" : "1312",
"accounts": [
{
"accountNumber":"8888",
"authorizationLevel":1,
"addressLine1":"898 Street",
"addressLine2":"Apt 102",
"city":"Stamford",
"state":"CT",
"zipcode":"60660",
"userCount":0
},
{
"accountNumber":"8688",
"authorizationLevel":1,
"addressLine1":"500 Street",
"addressLine2":"Apt 1",
"city":"Atlanta",
"state":"GA",
"zipcode":"60660",
"userCount":0
},
{
"accountNumber":"9999",
"authorizationLevel":3,
"addressLine1":"500 Street",
"addressLine2":"Apt 1",
"city":"Charlotte",
"state":"NC",
"zipcode":"60660",
"userCount":0
}
]
}

I am trying to match the user ID value within the type group and fetch the list of documents containing that user ID. I only want to fetch the required fields like groupID, accounts(List).

I used this and played around with a couple of options to get the required fields, but I end up getting the entire document
I tried termquery and also set the fetchsource value to false.
TermQuery didnot return any hits.

SearchResponse searchResp = client.prepareSearch(index)
.setTypes(type)
.setSearchType(SearchType.QUERY_AND_FETCH)
.setQuery(QueryBuilders.matchQuery("userID", "U1134"))
.execute()
.actionGet();

So when I tried to get the specific field from the map returned by getSource. I am getting parse exceptions while using Jackson to convert the JSON to a Java POJO.
On checking, when I used getSource, it removed all the quotes from the JSON document(compared to getSourceAsString) and I think that's causing issues in parsing.
I don't want to go down the path of traversing the tree structure of Jackson

Please advise if I am missing anything here.

Thanks

Use a TermQuery but lowercase your term or change the mapping to make this field not analyzed (better).

Can you give an example of what you get when you run getSource and then get your field?

If you do that BTW you can't transform it to JSON as it's only a String. May be I'm wrong but I don't understand all what you did.

May be describe with more code what you did?
