An in-memory Indexer implementation using bleve

Our first attempt at implementing an in-memory indexer will be based on a popular full-text search package for Go called bleve ^[1]. While bleve is primarily designed to store its index on disk, it also supports an in-memory index. This makes it an excellent candidate for running unit tests in isolation or for demonstration purposes if we don't want to spin up a much more resource-intensive option such as Elasticsearch.

The full source for the bleve-based Indexer implementation is available in the Chapter06/textindexer/store/memory package in this book's GitHub repository. The definition of the InMemoryBleveIndexer type is pretty straightforward:

type InMemoryBleveIndexer struct { mu sync.RWMutex ...
