---------------------------------------
Ok, I'll try to provide a patch in the coming weeks.
> Allows IOException in DocsEnum#freq()
> -------------------------------------
>
> Key: LUCENE-4046
> URL: https://issues.apache.org/jira/browse/LUCENE-4046
> Project: Lucene - Java
> Issue Type: Improvement
> Components: core/index
> Reporter: Renaud Delbru
> Assignee: Simon Willnauer
> Labels: codec, index
> Fix For: 4.0
>
>
> Currently, DocsEnum#freq() does not allow IOException. This is problematic if somebody
wants to implement a codec that allows lazy loading of freq. Frequency will be read and decoded
only when #freq() will be called, therefore calling IndexInput's read methods that can throw
IOException.
> The current workaround is to catch the IOException in freq() and ignore it (which is
not very nice and not a good solution).
