Shawn Heisey commented on LUCENE-6272:
--------------------------------------
I use eclipse. Hopefully one day I can switch, but haven't had enough time to
learn IntelliJ yet.
I haven't looked at everything that gets set by the idea/eclipse targets, but I
would have hoped that those targets would force all formatting templates at the
project level. I know that for eclipse, the general formatting (indentation,
etc) *is* set by the eclipse target.

>
> Scorer currently has to implement a whole bunch of methods that are never
> called. The only method that Scorer uses in addition to the methods on
> DocIdSetIterator is freq(), and as currently implemented this means different
> things on different Scorers:
> * TermScorer returns its underlying termfreq
> * MinShouldMatchScorer returns how many of its subscorers are matching
> * {Exact|Sloppy}PhraseScorer returns how many phrases it has found on a
> document
> In addition, freq() is never actually called on TermScorer, and it's only
> used in explain() on the phrase scorers.
> We should make Scorer extend DocIdSetIterator instead. In place of freq(),
> Scorer would have a coord() method that by default returns 1, and for boolean
> scorers returns how many subscorers are matching.
