About Storing and Displaying Dynamic Property Fields

If Store meta names is not selected for a dynamic property, the resulting dedicated index field (or category facet or output context) is the same as any other alphanumeric or numerical field created with standard properties. It contains only meta values.

Without Stored Meta Names

Note: The Store index field includes both the store_city and store_country metas, and displays the values for both together.

If Store meta names is selected, by contrast, the resulting index field (or category facet or output context) is indeed different from standard fields: for each value, it also stores the associated meta name. This allows you to search and retrieve specific metas within the field.

With Stored Meta Names

Note: The Store index field displays the store_city and store_country metas separately.

Dynamic properties, are not stored in the Categories index field with a /top/foo/bar tree structure like standard facets. To calculate their values, use virtual expressions, with the following syntax:

#extract(dynamicField, "<meta name>") to return the value of "meta name" in the dynamic field.
