In this chapter, you’ve learned how to perform basic searching using SET operations, and then ordered the results based on either values in HASHes, or potentially composite values with ZSETs. You continued through the steps necessary to build and update information in an ad-targeting network, and you finished with job searching that turned the idea of scoring search results on its head.
Though the problems introduced in this chapter may have been new, one thing that you should’ve gotten used to by now is Redis’s ability to help you solve an unexpectedly wide variety of problems. With the data modeling options available in other databases, you really only have one tool to work with. But with Redis, the five data structures and pub/sub are an entire toolbox for you to work with.
In the next chapter, we’ll continue to use Redis HASHes and ZSETs as building blocks in our construction of a fully functional Twitter clone.
