Why are spouses always relegated to a last but not least disclaimer? There is no doubt in our minds that the two people most deserving of our gratitude are Xavi Sánchez Catalán, Clinton’s long-suffering husband, and Genevieve Flanders, Zach’s fiancée. They have looked after us and loved us, picked up the slack, put up with our absence and our endless moaning about how long the book was taking, and, most importantly, they are still here.
Thank you to Shay Banon for creating Elasticsearch in the first place, and to Elastic the company for supporting our work on the book. Our colleagues at Elastic deserve a big thank you as well. They have helped us pick through the innards of Elasticsearch to really understand how it works, and they have been responsible for adding improvements and fixing inconsistencies that were brought to light by writing about them.
Two colleagues in particular deserve special mention:
- Robert Muir patiently shared his deep knowledge of search in general and Lucene in particular. Several chapters are the direct result of joining his pearls of wisdom into paragraphs.
- Adrien Grand dived deep into the code to answer question after question, and checked our explanations to ensure they make sense.
Thank you to O’Reilly for undertaking this project and working with us to make this book available online for free, to our editor Brian Anderson for cajoling us along gently, and to our kind and gentle reviewers Benjamin Devèze, Ivan Brusic, and Leo Lapworth. Your reassurances kept us hopeful.
Finally, we would like to thank our readers, some of whom we know only by their GitHub identities, who have taken the time to report problems, provide corrections, or suggest improvements:
