Based on reading the same comments you read, I'm pretty doubtful that
Codec.getDefault() is going to work. It seems to me that this
situation renders the FilterCodec a bit hard to to use, at least given
the 'every release deprecates a codec' sort of pattern.

Robert,
Let me lay out the scenario.
Hardware has .5T of Index is relatively small. Application profiling
shows a significant amount of time spent codec-ing.
Options as I see them:
1. Use DPF complete with the irritation of having to have this
spurious codec name in the on-disk format that has
WHOOPS.
First sentence was, until just before I clicked 'send',
Hardware has .5T of RAM. Index is relatively small (20g) ...

I think you can do it with 4 simple queries:
1) +flying +shooting
2) +flying +fighting
etc.
or BooleanQuery equivalents with MUST clauses. Use
aol.search.TotalHitCountCollector and it should be blazingly fast,
even if you have more that 100 docs.

Hi,
How about Codec.getDefault()? It does indeed not necessarily return the newest
one (if somebody changes the default using Codec.setDefault()), but for your
use case wrapping the current default one, it should be fine?
I have not tried this yet, but there might be a chicken-egg problem:
-
Honestly i dont agree. I don't know what you are trying to do, but if
you want file format backwards compat working, then you need a
different FilterCodec to match each lucene codec.
Otherwise your codec is broken from a back compat standpoint. Wrapping
the latest is an antipattern here.

Hi,
FYI, this is the same issues like Locales have/had in ICU! If you try to render
an error message in Locales's constructors, this breaks with NPE - because
default Locale is not yet there... I think they implemented some fallback
that is guaranteed to be there.
But this would not help you,

Might also look at concordance code on LUCENE-5317 and here:

Let me know if you have any questions.
