> Project: Lucene - Core
> Issue Type: Bug
> Reporter: Michael McCandless

> I'm working on a test that creates a biggish index and I noticed the
> CheckIndex takes a surprisingly long time to check term vectors.
> I profiled it and uncovered that we spend a lot of time (not sure this
> explains all of it) in Terms.getMin/getMax. Since
> CompressingTermVectorsReader doesn't impl these methods efficiently (which is
> fine), we fallback to super's impl, which does a digit-by-digit binary search
> using seekCeil.
> But for TVs this sometimes results in a linear scan.
> I think CheckIndex should not check Terms.getMin/Max for TVs?
