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 > ----------------------------------------------------------------------- > > Key: LUCENE-2317 > URL: https://issues.apache.org/jira/browse/LUCENE-2317 > Project: Lucene - Java > Issue Type: Improvement > Components: Index > Reporter: Michael McCandless > Fix For: 3.1 > > > [Spinoff of LUCENE-2308... we keep spinning things off...
