If you are not intented to index whole internet, there shouldn't be any

What is the limit of Lucene: # of docs per index?
In RangeFilter.Bits(), for example, it initializes a bitset to the size of
maxDoc from the indexReader. I wonder what happen if the # of docs is huge,
say MaxInt (4G in 32bit or 2^63 in 64 bit)?
