Search docs page is not comprehensive

[javanna]

I noticed that the search docs page at https://www.elastic.co/guide/en/elasticsearch/reference/current/search-search.html lists the elements that a search response can be made of, but the list is incomplete, for instance aggregations and fields are missing. I believe that rescore and sort are also missing in the request section. Maybe worth checking if anything else is missing.

Other missing parameters from the _search API reference page:

• min_compatible_shard_node (query parameter)
• collapse (body)
• highlight (body)
• post_filter (body)
• search_after (body)
• suggest (body)
• slice (body)
• sort (body)

This effort is probably not that relevant any more, as we're moving to generating the API reference docs from the spec (which does have all the parameters).
