In case you are upgrading to version 9.7 or higher and want to benefit from the full text search the aggregates that you already have stored in database must be indexed. As it is important that also system set attributes are indexed, this cannot be a database operation, and a filled runtime profile is needed. We have created a special service that allows you to just index aggregates without updating them in the database. The first step is to create the service definition in studio, and then call it in an appropriate flow.

Step-by-step guide to add the service

1. In Studio add a custom service named AQ_Aggregate_Index_Migrate
2. The service definition looks like this:
   
   
   
3. The aggregateId is always required.
   The aggregate version is optional. In case this is not specified, the latest version of an aggregate will be indexed.
    

   We need a service that is able to update an aggregate. This service has the following parameters:

    

   Parameter	Direction	Value	Data Type	Description	Fill
   AggregateType	Input	Module Element	Aggregate	Select the aggregate that you want to update.	Required
   AggregateID	Input	Expression	Integer	Please provide the attribute containing the ID of the aggregate entry to index.	Required
   AggregateVersion	Input	Expression	Integer	If a specific version of the aggregate needs to be updated. If not provided then the latest one is updated.	Optional
   StoreInstances	Input	Expression	Entity	Specify the starting point instance(s) used for storage.	Optional

    

   Event Name	Event Type	Description
   AppException	Cancel	The service takes this exit if indexing failed for some reason.
