Faceting

Faceting allows the user to group search results into categories based on the values of an attribute type. For example, you can group the search results based on the "Object Type" system attribute. You can get the numbers of objects in a category, e.g. Column, and find the objects of that category. Faceting makes it easy for users to explore search results, narrowing in on exactly the results they are looking for.
‎
‎ If the search index is a Solr index, many system attributes can be used in faceting. Refer to the Column "Supported in FACET" of System Attributes . Custom attributes of the following data types can also be used in faceting: Boolean, Integer, Date, DateTime, Enumeration, Enumeration (Multi-value), String, User and Users. To facet on a Date or DateTime attribute, a "Data Range Gap" parameter, such as YEAR, MONTH, DAY, or HOUR, must be provided.
‎
‎ If the search index is a Lucene index, only “Model Id” and "Object Type" system attributes can be used in faceting.
