Grails - ElasticSearch - QueryParsingException[[index] No query registered for [query]]; with elasticSearchHelper; JSON via curl works fine though - grails

Question

I have been working on a Grails project, clubbed with ElasticSearch ( v 20.6 ), with a custom build of elasticsearch-grails-plugin(to support geo_point indexing : v.20.6)
have been trying to do a filtered Search, while using script_fields (to calculate distance). Following is Closure & the generated JSON from the GXContentBuilder :
Closure
records = Domain.search(searchType:'dfs_query_and_fetch'){
query {
filtered = {
query = {
if(queryTxt){
query_string(query: queryTxt)
}else{
match_all {}
}
}
filter = {
geo_distance = {
distance = "${userDistance}km"
"location"{
lat = latlon[0]?:0.00
lon = latlon[1]?:0.00
}
}
}
}
}
script_fields = {
distance = {
script = "doc['location'].arcDistanceInKm($latlon)"
}
}
fields = ["_source"]
}
GXContentBuilder generated query JSON :
{
"query": {
"filtered": {
"query": {
"match_all": {}
},
"filter": {
"geo_distance": {
"distance": "5km",
"location": {
"lat": "37.752258",
"lon": "-121.949886"
}
}
}
}
},
"script_fields": {
"distance": {
"script": "doc['location'].arcDistanceInKm(37.752258, -121.949886)"
}
},
"fields": ["_source"]
}
The JSON query, using curl-way, works perfectly fine. But when I try to execute it from Groovy Code, I mean with this (taken from ElasticSearchService.groovy) where request is SearchRequest instance :
elasticSearchHelper.withElasticSearch { Client client ->
def response = client.search(request).actionGet()
}
It throws following error :
Failed to execute phase [dfs], total failure; shardFailures {[1][index][3]: SearchParseException[[index][3]: from[0],size[60]: Parse Failure [Failed to parse source [{"from":0,"size":60,"query_binary":"eyJxdWVyeSI6eyJmaWx0ZXJlZCI6eyJxdWVyeSI6eyJtYXRjaF9hbGwiOnt9fSwiZmlsdGVyIjp7Imdlb19kaXN0YW5jZSI6eyJkaXN0YW5jZSI6IjVrbSIsImNvbXBhbnkuYWRkcmVzcy5sb2NhdGlvbiI6eyJsYXQiOiIzNy43NTIyNTgiLCJsb24iOiItMTIxLjk0OTg4NiJ9fX19fSwic2NyaXB0X2ZpZWxkcyI6eyJkaXN0YW5jZSI6eyJzY3JpcHQiOiJkb2NbJ2NvbXBhbnkuYWRkcmVzcy5sb2NhdGlvbiddLmFyY0Rpc3RhbmNlSW5LbSgzNy43NTIyNTgsIC0xMjEuOTQ5ODg2KSJ9fSwiZmllbGRzIjpbIl9zb3VyY2UiXX0=","explain":true}]]]; nested: QueryParsingException[[index] No query registered for [query]]; }
The above Closure works if I only use filtered = { ... } script_fields = { ... } but it doesn't return the calculated distance.
Anyone had any similar problem ?
Thanks in advance :)
It's possible that I might have been dim to point out the obvious here :P
