In this chapter, we developed an understanding of inverted indices and implemented it for Librarian for the efficient storage and lookup of search terms. We also checked our implementation with the help of a script, feeder.go, and cURL commands.
In the next chapter, Chapter 8, Deploying Goophr, we will rewrite Concierge's api.indexAdder so that it can start sending the tokens to be indexed to Librarian. We will also revisit docker-compose.yaml so that we can have the complete application running and use/test it as a distributed system.
