I do use the online documentation for reference. At the same time, I would like to read book(s) which help understand Elastic Search (not LK) in-depth. Hope the book would cover following areas in-depth
- running at scale
I came across following books.
- Advanced Elasticsearch 7.0, 2019, ES7, https://www.amazon.co.uk/Advanced-Elasticsearch-7-0-practical-distributed/dp/1789957753
- Learning Elasticsearch, 2017, ES 5, https://www.amazon.co.uk/Learning-Elasticsearch-Structured-unstructured-distributed/dp/1787128458
- Elasticsearch: Definitive Guide, 2015, https://www.amazon.in/Elasticsearch-Clinton-Gormley/dp/9352132149/
- Mastering Elasticsearch - Second Edition, 2015, https://www.amazon.co.uk/Mastering-Elasticsearch-Second-Rafal-Kuc/dp/1783553790/
I see above books (1, 2) have few good reviews. Few books from 2015 (3, 4) have more good reviews, but they cover older version of Elastic search. Can fellow members including ES maintainers please suggest whether the older books are still a good read where most concepts would be still relevant? Please recommend if you know of a good book that is not in the list and is relevant even today (2020).
