I would like to thank my family for their continuous support, specially my brother, Patanjali Dixit, who always guided me at each step throughout my career. I would also like to give a big thanks to Lavleen for the support, patience, and encouragement she gave during all those days when I was busy writing this book.
I would like to extend my thanks to all of the Packt team working on this book and our technical reviewer, Alberto Paro. Without them, the book wouldn't have been as great as it is now. It was one of the best team i have worked with.
Finally, special thanks to Shay Banon for creating Elasticsearch and to all the people who contributed to the libraries and modules published around this project.
Once again, thank you.
