The Docs seach on elastic.co is weird

Hi,

Maybe from version 7.x it's really hard to find correct results in the docs. Here one example :
If I'm in the elasticsearch version 7.6 documentation page:
https://www.elastic.co/guide/en/elasticsearch/reference/current/index.html
and I search for the keyword "match_phrase" in the search bar no result match where I expect to have this page:

https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-match-query-phrase.html#

Another search is with keyword "boolean", "sort", "boost" which return results for painless doc. Where I expect to return result from the elasticsearch doc not the painless doc, as I'm the elasticsearch documentation page.

Maybe my search are not common, what I try to do is searching for some example to post on stackoverflow or forum for reference.

You may certainly have some logs that show you other example.
