Shai Erera commented on LUCENE-2317:
------------------------------------

This will turn into another setting. Can we introduce on the fly a setMatchOnly 
method which will turn all off (in addition to the one you're proposing)? Maybe 
it should become its own FieldType constant ... it will be bundling together a 
bunch of options that can be set individually if one wants finer grained 
control.

> allow separate control of whether docTermFreq and positions are indexed

> [Spinoff of LUCENE-2308... we keep spinning things off... I feel like we live 
> inside a particle accelerator]
> Right now Lucene indexes the docTermFreq and positions into the postings, by 
> default.
> You can use omitTFAP to turn them both off, which if you also omit norms 
> gives you "match only" scoring.
> But, really, they ought to be separately controllable -- one may want to 
> include docTermFreq but not positions, to get full scoring for non-positional 
> phrases.
> Probably we should wait until LUCENE-2308 is done, and make the API change on 
> *FieldType.
