Facet Filter about plainelastic.net

[Woland2k]

I added FilterFacet which allows defining filter facets as described here: http://www.elasticsearch.org/guide/reference/api/search/facets/filter-facet.html

Here is a new class:
https://github.com/Woland2k/PlainElastic.Net/blob/master/src/PlainElastic.Net/Builders/Queries/Facets/FilterFacet.cs

Now need to allow bool queries inside filters.

Thanks for feedback and for providing FilterFacet builder - I'll add it to facets builders.

This issue with FacetFilter happened because I haven't finished facets building yet. ( actually only Terms facet supported )
Anyway I've fixed FacetFilter generation, so now you can use code like this to apply custom filtering to any facet:

     var json  = 
        new QueryBuilder<ESDocument>()
                .Facets(facet => facet
                    .Terms(t => t
                        .FacetName("brand")
                        .Field("brand")
                        .FacetFilter(f => f
                            .Range(r => r
                                .Field("price")
                                .IncludeLower(false)
                                .IncludeUpper(true)
                                .From("Lower")
                                .To("Upper"))
                        )
                    )
                ).BuildBeautified();

this will generate the following JSON:

{
    "facets": {
        "brand": {
            "terms": {
                "field": "brand"
            },
            "facet_filter": {
                "range": {
                    "price": {
                        "include_lower": false,
                        "include_upper": true,
                        "from": "Lower",
                        "to": "Upper"
                    }
                }
            }
        }
    }
}

Great, I did implement some more Facet filtering including BoolFilter and FilterFacet if you want to include into the main code.

Thanks, I've added FilterFacet JSON builder will look at BoolFIlter.
