Hi,

I am trying to execute the following query from the gas filter neo4j example in [https://github.com/graphaware/graph-aided-search](https://github.com/graphaware/graph-aided-search). How to use the Nest DSL in forming the query below or do I have to send raw Json using the low level client.

{  
"query" : {  
"match\_all" : {}  
},  
"gas-filter" :{  
"name": "SearchResultCypherFilter",  
"query": "MATCH (cust:Customer)-[:PURCHASED]-\>(:Order)-[o:ORDERS]-\>(p:Product) WHERE cust.contactName = 'Maria Anders' RETURN DISTINCT p.productID as id;",  
"exclude": false  
}  
}

The high level NEST client won't be able to support that query, but you can use the low level client exposed on the high level client through the `.LowLevel` property for this

```
var query = @"{
  ""query"" : {
    ""match_all"" : {}
  },
  ""gas-filter"" :{
    ""name"": ""SearchResultCypherFilter"",
    ""query"": ""MATCH (cust:Customer)-[:PURCHASED]->(:Order)-[o:ORDERS]->(p:Product) WHERE cust.contactName = 'Maria Anders' RETURN DISTINCT p.productID as id;"",
    ""exclude"": false
  }
}";

var searchResponse = client.LowLevel.Search<SearchResponse<MyDocument>>(
    "index", 
    "type",
    query);

// will be SearchResponse<MyDocument>
var response = searchResponse.Body;

```

Nice thing about using the low level client on the high level client is that you can still return strongly typed responses.
