Structure

A numeric object field can be grouped into bands to allow refinements that represent a range of values. Prices is a good example of this. Grouping car prices into bands of 5,000 allows a user to see bands like “0-5000”, “”5001-10000”, etc. These bands can be displayed on a web page for ease of user selection to narrow a set of results.

An array of values for an object property can be defined as a list dimension. An example would be car features. A car might have “radial tires” but it will also have many other features. If the data store object has a list of features, many of which will be shared with other objects, this is a good example of a list dimension. This dimension type is useful to display a finite set of items where more than one can be associated with a single object.

A data store object can also have a GeoCode field. This data type is composed of a latitude/longitude pair that allows a query to be run to find all objects in a geographic area based on a radial search.
