David Smiley commented on SOLR-2883:
Terms' {{method}} doesn't change the semantic effects; it's only about
efficiency given different options.
This may be an old issue number but nonetheless I feel it's valid still.

Mikhail Khludnev commented on SOLR-2883:
This number is a little bit ancient. We already have {{filter(..)}} and
{{foo:bar^=1}}. But {{{!terms}}} is a little bit different question. It has
dedicated {{method}} switch which judges whether it will rewrite to score or
constant score filter.
