Building Read Models from Multiple Sources

The new Search module will return order data that should not require any additional queries to other services to be useful. We want to be able to return the customer’s name, product name, and store name in the details we return. We also want to be able to locate the orders using more than their identities.

The search goals of this new module are as follows:

• Search for orders belonging to specific customer identities.

• Search for orders by store and product identities.

• Search for orders created within a date range.

• Search for orders that have a total within a range.

• Search for orders by their status.

The read model that we will be building is not too different from what an order in the Order Processing module looks like:
