Robert Muir commented on LUCENE-4526:
-------------------------------------
I just glanced through in general: this is similar to the hack patch i used
exploring LUCENE-4089, though I just used a Map<String,String>.
The part i didnt like when exploring was more related to how term index/term
dictionary are separated:
{noformat}
divisor: generalize this into something simple like a Map<String,String> of
codec "parameters" that you set on IWC/IR. split divisor from "don't load terms
index". define these as constants where they belong. I got unhappy here in the
"splitting" part because I wanted the divisor part in TermsIndexReaderBase, but
that doesnt extend FieldsProducer (where i wanted the "don't load" part) and
wrap the terms dict, instead its backwards and terms dict wraps the
TermsIndexReaderBase... maybe we should fix that too? I think this confusing
the way it is but I didnt look at how difficult this would be.
{noformat}
But I think maybe I was trying to tackle too much at once... still as an
"untyped" parameter I thought it would be useful to fix the semantics all in
one break rather than causing confusion down the road.

> Today we expose termIndexInterval and termIndexDivisor via several APIs and
> they are deprecated. Those settings are 1. codec / postingformat specific and
> 2. not extendable. We should provide a more flexible way to pass information
> down to our codecs.
