Configure facets and filters

The configuration file is located in the Configs_folder and is called _Mediachase.Search.Filters.config. The 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 facets for that facet group.

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

SimpleValue. A string value.
- [key]. Attribute is not used but should be lowercase.
- [value]. The lookup key value; must be lowercase.
- Descriptions [defaultLocale]. Specifies which localized description is used if no localization is specified.
- Description [locale]. Specifies the culture code of the filter description.
- Description. The value to display in the SideMenu, based on the locale.
PriceRangeValue. Price ranges.
- [key]. The lookup key value; must 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 are included in the results.
- [upperboundincluded]. Must be true or false. It indicates whether the upperbound value is included in the filtered range.
RangeValue. 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. The numeric attribute is not relevant
- These values, including numeric values, are passed as string values to Lucene, which treats them as Double values.
- Attributes are a subset of the PriceRangeValue filter data type.
