Facet field

Feature

Create a facet range

How to

  1. Configure facet
    DocumentCollection<TechProductDocument> documentCollection; // from DI

    var rersult = documentCollection
        .Select()
        // gap: "1", start: "10", end: "100"
        .FacetRange("AliasName", q => q.Price, "1", "10", "100")
        .Execute();
  1. Optionally, change one or more settings
    DocumentCollection<TechProductDocument> documentCollection; // from DI

    var rersult = documentCollection
        .Select()
        .FacetRange("AliasName", q => q.Price, "1", "10", "100", facet =>
        {
            facet.Minimum = 3;
            facet.Limit = 5;
        })
        .Execute();
  1. Read data
    rersult
        .Facets(out var data);

    foreach (FacetItemRange facetItem in data)
    {
        // facetName = "AliasName"
        var facetName = facetItem.Name;
        //facetType = FacetType.Range
        var facetType = facetItem.FacetType;

        foreach (FacetItemRangeValue<decimal> facetItemValue in facetItem.Values)
        {
            // nested = nested facet (if configured)
            var nested = facetItemValue.Facets;
            // minimumValue = minimum value of item
            var minimumValue = facetItemValue.MinimumValue;
            // maximumValue = maximum value of item
            var maximumValue = facetItemValue.MaximumValue;
            // quantity = quantity of item's value
            var quantity = facetItemValue.Quantity;
        }
    }

Settings

Use case How to
Sort type of result of facet .FacetRange("AliasName", q => q.Price, "1", "10", "100", facet => facet.SortType(FacetSortType.CountAsc))
Minimum count of itens in facet's result .FacetRange("AliasName", q => q.Price, "1", "10", "100", facet => facet.Minimum(2))
Limit of itens in facet's result .FacetRange("AliasName", q => q.Price, "1", "10", "100", facet => facet.Limit(10))
List of tags to exclude in facet calculation .FacetRange("AliasName", q => q.Price, "1", "10", "100", facet => facet.Excludes(new[] { "tag1", "tag2" }))
Counts should also be computed for all records with field values lower then lower bound of the first range .FacetRange("AliasName", q => q.Price, "1", "10", "100", facet => facet.CountBefore(true))
Counts should also be computed for all records with field values greater then the upper bound of the last range .FacetRange("AliasName", q => q.Price, "1", "10", "100", facet => facet.CountAfter(true))
Specify a filter or list of filters to be intersected with the incoming domain before faceting .FacetRange("AliasName", q => q.Price, "1", "10", "100", facet => facet.Filter(f => f.Field(q => q.Id).EqualsTo(10)))
