This topic describes the various parts of the configuration elements related to facets and filters in Episerver Commerce. The configuration file is located in the Configs folder and is called Mediachase.Search.Filters.config.

Configuration elements

The configuration file contains the following elements:

  • Filter is the Facet Group.
  • Filter [field] is the name of the field/meta-field being filtered.
  • Filter/Description contains the localized text for a facet group. This determines what is displayed at the top of the side menu.
  • Filter/Values contains all of the facets for that facet group.

Facet types

Each facet group should only have one type of facet. The different facet types are described below.

    • SimpleValue. A string value.
      • [key]. Attribute is not used but should be lowercase.
      • [value]. The lookup key value; must always be lowercase.
      • .Description [defaultLocale]. Specifies which localized description is used where no localization is specified.
      • .Description .Description [locale]. Specifies the culture code of the filter description.
      • .Description .Description. The value to display in the SideMenu, based on the locale.
    • PriceRangeValue. Price ranges.
      • [key]. The lookup key value; must always be lowercase. The options are under-number, number-number, and over-number.
      • [currency]. A three-character currency code that corresponds to the code selected in the tiered pricing collection of a SKU.
      • [lowerbound]. The numeric lower end of the range.
      • [upperbound]. The numeric upper end of the range.
      • [lowerboundincluded]. Must be true or false. It indicates whether the lower-bound value is included in the filtered range. For example, if lowerboundincluded is set to true for a $200-$300 filter range, items that are exactly $200 would be included in the results.
      • [upperboundincluded]. Must be true or false. It indicates whether the upperbound value is included in the filtered range.
    . Numeric ranges; values must be 0-10.
    • This type matches a range of numeric values.
    • This filter data type only supports values less than 10.
    • If a numeric type like float or decimal is used in defining the meta-class, an additional attribute setting, you must use  numeric=true.
    • You can use a string meta-field type and the numeric attribute is not relevant.
    • These values, including numeric values, are passed as string values to Lucene, which then treats theme as Double values.
    • Attributes are a subset of the PriceRangeValue filter data type.
