Get X word before and after search word


(Petr Janský) #1

Hello,

I'm trying to find way how to get words/terms around search word eg let's
have a document with text "The best search engine is ElasticSearch". I will
search for "best" and get info that word "search" is xtime the next one
after search words.

Thx
Petr

Hey,

you potentially could use the termvectors API for this, see
http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/docs-termvectors.html

Not sure, if this is excalty, what you are after... maybe explain your
use-case a bit more

Span queries are another option, but the main drawback is that they use
non-analyzed term queries.
