Jack Krupansky commented on SOLR-5116:
--------------------------------------
Is that really going to be faster that doing the filter query that was
discussed?
And... supposedly the filter query was going to be faster for the negative
form, -field:*, at least that's what Uwe originally led me to believe.
> Rewrite field:* as if field:[* TO *] so field type can optimize

> The queries {{field:*}} and {{field:[* TO *]}} are semantically equivalent
> but the latter is potentially must faster since the field type can intercept
> it to return a more optimal implementation than a brute force scan of the
> terms. The trie numeric fields do this. The spatial ones don't but they
> could be rewritten easily to do so.
