Mykhailo Demianenko commented on LUCENE-7999:
---------------------------------------------

Thank you! [~mikemccand] Unfortunately I do not have precise information on how old this particular
index was (most probably a couple of years). But yes we refresh indexes quite a lot since
we need to ensure that readers always see the latest available snapshot of the data.
