c# - How to Pass Raw JSON to RegisterPercolator in ElasticSearch NEST? -

i trying create object-agnostic percolator microservice in c#. can create , map index passed method using json object mapping, can register percolator against index using standard nest query format, such this:

var percolateresponse = client.registerpercolator<dynamic>(query     .name, p=>p         .index(index.actualname)         .query(q=>q             .term(t=>t                 .onfield("banana")                 .value("green")))); 

the problem is, need able pass in json of query , i've been trying use following code:

var percolateresponse = client.registerpercolator<dynamic>(query     .name, p=>p         .index(index.actualname)         .query(q=>q.raw(query.context))); 

the json passing in is:

{"query":     {"term":         {"banana":             {"value": "green"}         }     } } 

what happening though, instead of registering specified query percolator query, sets query value of registerpercolatorrequest null , cancels out query if exists.

i have tried number of different formats of json, , have not found .query(q=>q.raw(query.context)) liked.

does know how solve this? have moved closer , closer solution this, never quite gotten past 1 issue. last remaining roadblock creating percolator proxy class. appreciated. thanks.

just reference, error getting (deep inside response object) this:

[<indexname>] failed parse query [<queryname>]];  nested: queryparsingexception[[<indexname>] [_na] query malformed,  no field after start_object

i think have found solution trying do... above query didn't work, through trial , error, have found out work take in object-agnostic query , register percolator:

var percolateresponse = client.registerpercolator<dynamic>(query     .name, p => p         .index(index.actualname)         .query(q => q             .simplequerystring(sqs=>sqs                 .query(query.context)))); 

this creates query simple query string , stores such in elasticsearch, , appears work when try percolate document match query!
