About the Cover Illustration

The figure on the cover of Elasticsearch in Action is captioned “A man from Croatia.” The illustration is taken from a reproduction of an album of Croatian traditional costumes from the mid-nineteenth century by Nikola Arsenovic, published by the Ethnographic Museum in Split, Croatia, in 2003. The illustrations were obtained from a helpful librarian at the Ethnographic Museum in Split, itself situated in the Roman core of the medieval center of the town: the ruins of Emperor Diocletian’s retirement palace from around AD 304. The book includes finely colored illustrations of figures from different regions of Croatia, accompanied by descriptions of the costumes and of everyday life.

Dress codes and lifestyles have changed over the last 200 years, and the diversity by region, so rich at the time, has faded away. It is now hard to tell apart the inhabitants of different continents, let alone of different hamlets or towns separated by only a few miles. Perhaps we have traded cultural diversity for a more varied personal life—certainly for a more varied and fast-paced technological life.

Manning celebrates the inventiveness and initiative of the computer business with book covers based on the rich diversity of regional life of two centuries ago, brought back to life by illustrations from old books and collections like this one.

Part 1.

In this part, we will cover what Elasticsearch can do for you in terms of functionality. We’ll start with more general concepts in chapter 1, where we’ll explore how Elasticsearch is typically used as a search engine, and then move on to how to model, index, search, and analyze data efficiently. By the end of part 1, you’ll have a deep understanding of what Elasticsearch can offer from a functionality standpoint and how you can use it to solve your search and real-time analytics problems.
