Alias IDs enable you to associate a property or class in one object store with an equivalent property or class in another object store.
By assigning alias IDs, you enable support for multi-object store searches.
Only user-defined and built-in properties and classes can be aliased. System classes cannot be aliased.
An object in one object store can only be aliased to one object in another object store. The mapping must be one-to-one between object stores. Aliasing creates an association between objects in different object stores which are functionally identical, and there should only be one of those in each object store.
TIP When entering an alias ID, include the curly braces ( { } ). These braces are part of the Primary ID.
Aliasing Properties
To perform a cross object store search and retrieve the same value for equivalent properties in each of the object stores, create an alias between the properties.
NOTE If you add an alias ID to a property template already assigned to a class, the alias ID is not automatically applied to that class property. You must manually assign the alias ID to the class property.
To assign an alias ID to a property:
To assign an alias ID to a property once it is assigned to a class:
Aliasing Classes
When creating a cross object store search in Search Designer that filters by document class, the software expects the document class to exist in all the object stores against which you are searching. When the search executes, the software looks for all the document class filters in all the object stores specified for the search, using aliasing to resolve equivalent classes.
To assign an alias ID to a class:
Example of aliasing properties and filtering by document class
In this example, you have two object stores, OS1 and OS2. Both object stores have a functionally equivalent property called SSN.
Object store OS1 has a class, Data1, and object store OS2 has a class called Data2. The SSN property was added to each class.
To create a search in the Search Designer that retrieves documents from both object stores where the SSN number is the same, filtering by Data1 and Data2:
Documents with the class Data1 in OS1 and Data2 in OS2 where SSN equals the specified value are returned.
