Overview of this book

C++ has evolved over the years and the latest release – C++20 – is now available. Since C++11, C++ has been constantly enhancing the language feature set. With the new version, you’ll explore an array of features such as concepts, modules, ranges, and coroutines. This book will be your guide to learning the intricacies of the language, techniques, C++ tools, and the new features introduced in C++20, while also helping you apply these when building modern and resilient software. You’ll start by exploring the latest features of C++, and then move on to advanced techniques such as multithreading, concurrency, debugging, monitoring, and high-performance programming. The book will delve into object-oriented programming principles and the C++ Standard Template Library, and even show you how to create custom templates. After this, you’ll learn about different approaches such as test-driven development (TDD), behavior-driven development (BDD), and domain-driven design (DDD), before taking a look at the coding best practices and design patterns essential for building professional-grade applications. Toward the end of the book, you will gain useful insights into the recent C++ advancements in AI and machine learning. By the end of this C++ programming book, you’ll have gained expertise in real-world application development, including the process of designing complex software.

Summary

Building a search engine from scratch is a task for seasoned programmers. We have touched on many topics in this book and combined most of them in this chapter by designing a search engine.

We have learned that web search engines are complex systems consisting of several components, such as the crawler, the indexer, and user interface. The crawler is responsible for regularly checking the web to download web pages for the search engine to index. Indexing results in the production of a big data structure called an inverted index. An inverted index, or just an index, is a data structure that maps words with the documents in which they have occurred.

Next, we defined what a recommendation engine is and tried to design a simple one for our search engine. The recommendation engine was connected to the dialog-based features of the search engine discussed in this chapter. A...
