I use Lucene.Net with 10s of millions of docs without a problem. If you are not intented to index whole internet, there shouldn't be any problem.

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)?
