Filter facets
Describes how facets based on filters are used in Optimizely Search & Navigation.
Facets group documents based on criteria, such as specific terms or date ranges.Â
A filter facet returns a count of search results that match a filter. The filter can be an expression used with the Filter method, ranging from a single criterion to complex criteria of multiple sub-criteria.
To request a filter facet, use the FilterFacet
method has two parameters: name and filter or filter expression. You retrieve the resulting facet from the search results object using a method with the same name but with only a name parameter. The returned object has a single property, Count
, the number of documents matching the search query and filter.
The following example shows a sample search for products that requests and retrieves the value from two filter facets.
var result = client.Search<Product>()
.FilterFacet("In stock", x => x.InStock.Match(true))
.FilterFacet("In stock on sale",
x => x.InStock.Match(true) & x.OnSale.Match(true))
.GetResult()
int inStock = result.FilterFacet("In stock").Count;
int inStockAndOnSale = result
.FilterFacet("In stock on sale").Count;
