The central component of the Search model metadata is the Query Facts query subject.
Query Facts uses the following platform query subjects: External User (see User Metadata), Time, Date, Language, and Demographic, which in turn uses Region, Country, Marital Status, Age Group, Segment Cluster, and Gender (see the Platform Metadata Model chapter for information on these query subjects). It also uses the Internal User and Internal Organization query subjects (see the Internal User Directory Metadata chapter).
Additional Search query subjects are shown in the diagram that follows.
