Grant Ingersoll commented on LUCENE-1909:
-----------------------------------------
Boy, I had an awesome use case when I wrote this up, but am forgetting it now.
I think it was something like:
If you are examining the index ahead of time, you could have heuristics about
how much memory you want the system to use when loading a reader. Thus, I
could have a clause in my IndexReader code that did something like:
{code}
if (index is big){
reader = IndexReader.open(..., largerTermsIndexDiv);
} else{
reader = IndexReader.opent(..., DEFAULT_TERMS_INDEX_DIVISOR);
}
{code}
Hard coding a 1 in that else clause seems like a bad thing to do given there is
already a "default" value spec. by Lucene.
Also, since it is package private, if I extend IndexReader, I won't have access
to it.
At the end of the day, it's not a big deal.
> Make IndexReader.DEFAULT_TERMS_INDEX_DIVISOR public
