Hello everyone, I am presenting my book "*Inside Solr and Lucene: **Algorithms and Engineering Deep Dive*". (*I have three books out on Amazon—it just so happened that they were released simultaneously, and there's synergy there - all of them are about Search & Recsys*).
You are all developers, I hope you will find it useful. "Inside Solr and Lucene" differs from others on the topic of Solr/Lucene in that it describes the algorithms and data structures used there, starting from the problem that faced the developers, then examining naive or straightforward solutions, and further sharing how the architects in Solr/Lucene solved the problem. In very many cases, these are interesting, science-intensive solutions, backed by scientific works and papers (links are available in the book). https://testmysearch.com/books/inside-solr.html For example, I talk not only about the inverted index, posting lists, and how segments are stored—you can find it in other books—but also about how Finite-State Transducer (FST) is used there (this is a graph-based structure for term dictionaries, storing terms and metadata with shared prefixes/suffixes, solving high-memory usage and slow prefix/range queries in large vocabularies by providing compact, O(length of term) lookups); I talk about Pulsing Codec, Delta Encoding, Skip Lists, PackedInts (bit-packing algorithm that uses minimal bits per integer block based on the maximum value), Variable-Length Integers, LSM-Tree, HNSW for vectors, Roaring Bitmaps, LZ4 and DEFLATE compressions, Memory-Mapped I/O, Scatter-Gather Query Execution, Hash-Based Routing, SIMD Vectorization and a lot of other things of this kind. For solution architects and search engineers. Paperback and e-book versions. Worldwide delivery. I hope you will find it useful. P.S. I am currently working on the second edition of the book. Please let me know if you have something to add or change in it. -- Rauf Aliev, [email protected], Phone +15713428492 (EST) https://testmysearch.com/raufaliev https://testmysearch.com https://hybrismart.com -- Rauf Aliev, [email protected], Phone +15713428492 (EST) https://testmysearch.com/raufaliev https://testmysearch.com https://hybrismart.com
