Please correct me if I am wrong, but I think the prefix query finds
matching terms first and puts them in an array???
So if you have a numeric field, searching for 1* could give a near
infinite number - causing an OOM.
Causes me to think though... in most cases the number of unique names
that start with r should be relatively small - not enough to cause an
OOM - so I need to investigate further what is happening.

we use this for name searching, so that you might have

the problem being that the phrase "engels r" is quite unique, but
the term r* is not unique at all.
Anything improve the handling of this in the current lucene?
You could tokenize differently and index pairs together. Think
searching for "engles_r*".
If that's not an option, make sure that those two are being joined
via AND -- I think that will trigger the skipTo optimization when
the posting lists for r* are scanned.
