Hi guys,
I had a need to know how many deleted documents are in the index. I noticed
there isn't an API for it in IndexReader, however the information can be
obtained by calling IndexReader.maxDoc() - IndexReader.numDocs().
Do you think it's worth adding such an API to IndexReader?
Cheers,
Shai

, so calling it twice won't be a performance
killer, esp. since this is not something you'd call frequently, I imagine.
However, I do agree about numDeletedDocs() being nice for hiding implementation
details.

mpat (adds new abstract method to IndexReader).
Why don't we fallback to default impl, in IndexReader, of maxDoc() - numDocs()?
Patch is much less invasive, and, we don't break back compat? maxDoc() is
indeed cheap.

xDoc() - numDocs(). Not all extended
classes implement it this way BTW. SegmentReader just calls
deletedDocs.count(), rather then calling the two separate methods.

As for extending classes, I agree that calling two methods has little
performance overhead, but it just looks cleaner (for SegmentReader for
example). Anyway, I don't have a strong opinion on whether we should override
or not. I'll be fine with either.
