I got call from a recruiter for an elasticsearch job. I am not sure how these 2 are related. Can anyone suggest and provide example use case?

  • $\begingroup$ ElasticSearch is a text search engine as can serve as a database. Simple use case can be as simple as providing recommendations based on input text like lyric search etc. $\endgroup$ Commented Sep 20, 2017 at 6:00

Natural language processing (NLP) is a field of computer science, artificial intelligence, and computational linguistics.

ElasticSearch is a search engine based on Lucene.

ElasticSearch uses parts of NLP (e.g., tokenization and stemming). ElasticSearch also includes software engineering elements to ensure a search solution is performant.

Since NLP is entire discipline, there are many parts of NLP that are not related to ElasticSearch.

  • $\begingroup$ Most NLP components of Elasticsearch are inherited from Lucene -en.wikipedia.org/wiki/Apache_Lucene. $\endgroup$ Commented Sep 21, 2017 at 16:25
