Raw queries joined with NEST QueryContainer do not serialize.

[JefStat]

Combining multiple queries into a single boolean query but the query generated is empty for the queries that are created from a raw string.

With this method call

ConvertQueryToESD("{\"term\":\"fieldname\":\"value\"}"
                  ,null
                  ,a range filter)
    .From(0)
    .Take(50)
    .SortMulti(a sort)

 internal SearchDescriptor<T> ConvertQueryToESD<T>(string queryString, string filterId, List<QueryContainer> filters) where T : class
    {
        var filterQueryString = GetFilter(filterId);
        if (!string.IsNullOrWhiteSpace(filterQueryString))
        {
            var qd = new QueryDescriptor<T>();
            filters.Add(qd.Raw(filterQueryString));
        }
        if (!string.IsNullOrWhiteSpace(queryString))
        {
            var qd = new QueryDescriptor<T>();
            filters.Add(qd.Raw(queryString));
        }
        var sd = new SearchDescriptor<T>();
        sd.Query(q => q.Bool(b => b.Must(filters.ToArray())));
        return sd;
    }

Resulting query is

{
  "from": 0,
  "size": 50,
  "sort": [
    {
      "startTimeLocal": {
        "order": "desc"
      }
    }
  ],
  "query": {
    "bool": {
      "must": [
        {
          "range": {
            "startTimeLocal": {
              "gte": "0001-01-01T00:00:00",
              "lte": "2015-12-22T16:28:22"
            }
          }
        },
        {}
      ]
    }
  }
}

The {} is where I would expect to see the raw term query. Inspecting the SearchDescriptor before the search is ran shows all the expected fields are populated with the correct values. I have also tested only adding the raw string term query without the range filter and the search descriptor serializes as expected

Thanks for reporting this, the query.raw() is not well tested as a composable piece in 1.x and even in 2.x for now.

I just spend some cycles making sure this works in the upcoming 2.0 release (see https://github.com/elastic/elasticsearch-net/blob/9beac06934cf64cced512aca3ecde5cba1a55219/src/Tests/QueryDsl/NestSpecific/Raw/RawCombineUsageTests.cs).

The raw query now looks and behaves like any other IQuery albeit that's its the only one not supporting deserialization. Because of this I'm not planning to backport this to 1.x.

Raw() should be documented as a last ditch effort that does not combine well though in the 1.x branch though.

Thanks, waiting anxiously for the 2.0 release, guess we will test with a custom nuget pkg.

Closing this because we will phase out the 1.x documentation and in 2.x this is no longer a problem.
