- softwaredoug 9y agoI might shamelessly plug my own book, Relevant Search (http://Manning.com/books/relevant-search http://Manning.com/books/relevant-search) which introduces relevance on Elasticsearch. Ping me (http://o19s.com/doug http://o19s.com/doug) if you’d like a discount code!
- sandGorgon 9y agohere - https://www.elastic.co/guide/en/elasticsearch/reference/current/index-modules-similarity.html https://www.elastic.co/guide/en/elasticsearch/reference/curr... similarity/relevance is the mathematical difference between search and database query. Its an inexact match.
- pauloxnet 9y agoThanks. I'll read it.
- burntsushi 9y agoIf you want to reason about these things from first principles, then I recommend the IR book, which is free online: https://nlp.stanford.edu/IR-book/ https://nlp.stanford.edu/IR-book/
- rpedela 9y agoDepending on the ES version, it either does TF/IDF (older versions) or BM25 (newer versions) by default. You have to explicitly disable it if you don't want it. https://www.elastic.co/guide/en/elasticsearch/reference/current/index-modules-similarity.html https://www.elastic.co/guide/en/elasticsearch/reference/curr...
