Subject [jira] [Updated] (LUCENE-4496) Don't decode unnecessary freq blocks in 4.1 codec
Date Mon, 22 Oct 2012 15:08:12 GMT

     [ https://issues.apache.org/jira/browse/LUCENE-4496?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Robert Muir updated LUCENE-4496:
--------------------------------

    Attachment: LUCENE-4496.patch

Same patch, adding a few comments and beefing up TestBlockPostingsFormat3 to also check the
freqs case.

I'll commit this shortly after running some more tests, and I think I want to now yank TestBlockPostingsFormat3
out of this package and let it run with any codec, it just tests these various "subset" cases
and isnt specific to this PF.

> TermsEnum.docs() has an expert flag to specify you don't require frequencies. This is
currently set by some things that don't need it: we should call ForUtil.skipBlock instead
of ForUtil.readBlock in this case.
