Description

We have diverged from Lucene by replacing the NamedSPILoader and SPIClassIterator with abstract factories to load codec types (possibly from a dependency injection container). While the API docs are mostly complete, they are missing usage samples of how to extend the factories to register custom codec, doc values format, and postings format types.
