> 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).
