Thanks Alexander, but that won't do. The main requirement to keep
performance and size low is to have a really short document_id. With
base64 you can number 16 millions of documents with just 4 characters,
and over 1 thousand million documents with 5 characters. The number of
characters in the doc_id is really a critical parameter when dealing
with lots of documents.
