Previously created optimizations:
Allow significant_text to only parse out the specific field it requires from
_source
. This allows for a minor optimization when_source
is small, but can be significant (pun intended) when_source
contains many fields, or other larger fields thatsignificant_text
doesn't care about.Since
significant_text
does not allow sub-aggs, not caching the parsed_source
is reasonable.
