Can ElasticSearch return relevant passages and not the entire document

问题

I'm looking for a search engine that is able to return just relevant passages as a result and not the entire documents. Is ElasticSearch able to do this?

If you are looking to extract part of a long document, look at Highlighting. Specifically parameters like fragment_size (100 characters by default) or boundary_chars will help you to build that functionality.
