How to
Sort type of result of facet
.FacetSpatial("AliasName", q => q.StoredAt, new GeoCoordinate(1, 1), 10, facet => facet.SortType(FacetSortType.CountAsc))
Minimum count of itens in facet's result
.FacetSpatial("AliasName", q => q.StoredAt, new GeoCoordinate(1, 1), 10, facet => facet.Minimum(2))
Limit of itens in facet's result
.FacetSpatial("AliasName", q => q.StoredAt, new GeoCoordinate(1, 1), 10, facet => facet.Limit(10))
List of tags to exclude in facet calculation
.FacetSpatial("AliasName", q => q.StoredAt, new GeoCoordinate(1, 1), 10, facet => facet.Excludes(new[] { "tag1", "tag2" }))
Function used in spatial filter
.FacetSpatial("AliasName", q => q.StoredAt, new GeoCoordinate(1, 1), 10, facet => facet.FunctionType(SpatialFunctionType.Bbox))
Specify a filter or list of filters to be intersected with the incoming domain before faceting
.FacetSpatial("AliasName", q => q.StoredAt, new GeoCoordinate(1, 1), 10, facet => facet.Filter(f => f.Field(q => q.Id).EqualsTo(10)))
