Unfortunately, live searching against an old index can get very hairy.
EG look at what I had to do for the flex API on pre-flex index flex
emulation layer.
It's also not great because it gives the illusion that all is good,
yet, you've taken a silent hit (up to ~10% or so) in your search
perf.

Flex has already landed (in trunk, for 3.1), so this is just a
matter of someone creating a codec using Group VarInt.

Ugh, I'll fix this.
With the new flex API, you can't ask a composite (Multi/DirReader) for
its postings -- you have to go through the static methods on
MultiFields. I'm trying to put some distance b/w IndexReader and
composite readers... because I'd like to eventually deprecate them.
Ie, the

Which is not very readable, but, it does this because flex terms are
arbitrary byte[], not necessarily utf8... maybe we should fix it to
print both hex and String if we assume bytes are utf8?

It's also slow because it repeats all the tests for each of the core

I think it's fine to reduce the number of iterations -- just make sure

effective.
