Create powerful blockchain queries with Hyperledger Composer

With the native, rich Query language in Hyperledger Composer, it’s easy
to perform complex and powerful queries on assets, transactions, and other
resources. First, you model the query using Hyperledger Composer, and the
query is deployed to the runtime Hyperledger Fabric. All that’s left is to for
you to consume the query by name in your application. You can also easily
consume queries using REST APIs that are auto-generated by Hyperledger
Composer. Without this capability, you’d have to construct ad hoc queries in
your code and then labor to make sense of the results returned.
