Querying data using semantic types
Semantic types can be used to search for data in several different entity types or link types in a single query. You can also use semantic types to search a number of fields in different entity or link types that contain the same kind of information.
- Entity and link semantic types. You can search across several entity or link types that all represent the same sort of information.
- Property semantic types. You can search fields across different entity or link types which may be called different things but contain the same sort of information.
Constructing a query that contains semantic types
You construct a query that uses semantic types in the same way as you would create any other query. You can:
- Specify the semantic type for an entity or link type in the query structure area.
- Use a property semantic type for a condition in the Conditions area.
Viewing the scope of a query that contains semantic types
When you view the results of a query that includes semantic types it is useful to see exactly which entity types, link types and fields are searched. Unlike other queries, when you use a semantic type, you do not necessarily know before the query is run which types and fields are included in the query. You can use the scope to view a list of the searched items.
