Facet spatial

Feature

Create a facet spatial

How to

  1. Configure facet

    DocumentCollection<TechProductDocument> documentCollection; // from DI

    var rersult = documentCollection
        .Select()
        .FacetSpatial("AliasName", q => q.StoredAt, new GeoCoordinate(1, 1), 10)
        .Execute();
  1. Optionally, change one or more settings

    DocumentCollection<TechProductDocument> documentCollection; // from DI

    var rersult = documentCollection
        .Select()
        .FacetSpatial("AliasName", q => q.StoredAt, new GeoCoordinate(1, 1), 10, facet =>
        {
            facet.Minimum = 3;
            facet.Limit = 5;
        })
        .Execute();
  1. Read data

    rersult
        .Facets(out var data);

    foreach (FacetItemField facetItem in data)
    {
        // facetName = "InStock" or some alias (if configured)
        var facetName = facetItem.Name;
        //facetType = FacetType.Field
        var facetType = facetItem.FacetType;

        foreach (FacetItemQuery facetItem in data)
        {
            // facetName = "AliasName"
            var facetName = facetItem.Name;
            //facetType = FacetType.Query
            var facetType = facetItem.FacetType;
            // nested = nested facet (if configured)
            var nested = facetItem.Facets;
            // quantity = quantity of item's value
            var quantity = facetItem.Quantity;
        }
    }

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)
