The DCM Lists application receives updates from the case engine when cases or tasks are updated. If you start using the DCM Lists application and you already have a database with cases and tasks, you want these cases and tasks to show up in the lists, regardless if they are updated or not. To achieve this, you can use the initial indexing API.

Initial indexing API for DCM Lists

This endpoint publishes all cases and tasks as events to the DCM Lists application, via a queue. This endpoint needs to be enabled in configuration using the following property in the application-dcm-lists-publisher.properties of the case-engine:

...

Execution may take quite some time, depending on the number of cases. The progress of the indexing will be written to the log file on INFO level.

Preconditions

1. No other users should use the runtime
2. The Blueriq DCM Lists Service should be running and configured properly
3. The property blueriq.dcm.lists-publisher.indexing.enabled  should be set to true.
4. The endpoint uses the same authentication as other components in the Case Engine, see Blueriq Case Engine. 
5. This endpoint is designed to be used only once.
   1. If the indexing fails, you can use this endpoint again if you drop empty the cases and tasks collections in MongoDB.
6. The application ID that is stored with each case should resolve to a valid Blueriq project, according to the algorithm that is explained in the section about Migration API. If no project exists or if the project is not valid, the case and its tasks will be skipped.

Collation

Emptying collections and collation

When you manually drop Dropping the cases and task collections in MongoDB also means that the collation is lost. Which and then have Mongo create the collections automatically (this happens when you insert something in the collection), the collation of these automatically created collections is set to default. This has the effect that searches in the dcm-lists DCM Lists service are not case-insesitive insensitive anymore. When possible try to only That is why we advise to empty the collctions collections instead of dropping them. If you still need to keep the correct collation. To drop the collections, re-create them with the correct collation do using one of the following steps:

• When After the collections are dropped, restart the dcm-lists DCM Lists application. This will trigger the creation of The DCM Lists application will create the collections with the correct collation .when they do not exist at startup
• When the collections are dropppeddropped, manually recreate them re-create the collections with the correct collation.:

The correct collation is

collation: { locale: <your locale>, strength: 2 } }
