Mark Miller commented on LUCENE-1909:
-------------------------------------
I know its not a big deal - but I have an abrasive reputation to maintain ;)
The default terms info divisor essentially means that feature is turned off.
The 1 just means, don't sub sample the terms index. Its off.
For your use case, I would do:
{code}
if (index is big or memory is tight){
reader = IndexReader.open(..., largerTermsIndexDiv);
} else{
reader = IndexReader.open(...);
}
{code}
If you don't use that argument, you get the default. Whenever I see an issue to
open up something in Lucene without a reason that makes sense to me, I think
its a good idea to push back. If it really does make sense, it will make it
through - but I don't think anything should get a free pass. This one is still
not making sense to me.
Your right - its not a big deal - but I still don't see a reason to open it up.
