A port of the ElasticSearch Query DSL into .NET..

This was done mainly as the other .NET ElasticSearch clients (NEST & ElasticSearch.NET) don't have very complete DSLs currently. This one should be complete (if I've missed any features please let me know).

This is a direct port of the Java with the odd bit of .NET-ness here and there for convenience.

Features:

• Querying
• Faceting
• Filtering
• Sorting
• Highlighting

Example

var sb = SearchBuilder.Builder()
    .Query(QueryFactory.TermQuery("name", "fred"))
    .Sort(SortFactory.ScoreSort())
    .Facet(FacetFactory.RangeFacet("range")
        .AddRange(22, 345)
        .Field("distance"))
    .Filter(FilterFactory.BoolFilter()
                .Must(FilterFactory.TermFilter("name.first", "shay1"))
                .Must(FilterFactory.TermFilter("name.first", "shay4"))
                .MustNot(FilterFactory.TermFilter("name.first", "shay2"))
                .Should(FilterFactory.TermFilter("name.first", "shay3")));

Example (with NEST)

var elasticSettings = new ConnectionSettings("127.0.0.1.", 9200).SetDefaultIndex("mpdreamz");
var client = new ElasticClient(elasticSettings);

var query = QueryFactory
    .TermQuery("name", "Fred")
    .Boost(10);

var filter = FilterFactory.GeoDistanceFilter("name")
    .Point(10, 20)
    .Distance(10, DistanceUnit.MILES)
    .FilterName("filtername")
    .Cache(true)
    .CacheKey("cache_key");

client.Search<ExampleResult>(t => t
    .Filter(filter.ToString())
    .Query(query.ToString())
);

This is not a client .. just a way to construct JSON queries that can be processed by ElasticSearch.
