Michael McCandless commented on LUCENE-4515:
--------------------------------------------
Maybe rename "maxBufferedBytes" to "maxReusedBytes"? (Because it says how many
bytes can be retained even after reset is called).
I still don't like bringing allocation issues (even a long maxReusedBytes) into
our APIs: this is Java. But since this is package private I guess it's OK.
Can we default it to 0 not 5 MB? I think on reset() it's very unexpected that
this class would still hold onto 5 MB RAM ...
Why does reset() pass true for reuseFirst...?

> Currently MemoryIndex uses BytesRef objects to represent terms and holds an
> int[] per term per field to represent postings. For highlighting this creates
> a ton of objects for each search that 1. need to be GCed and 2. can't be
> reused.
