Do you mean that deleted document ids won't be reutilized, so the index
maxDoc will grow more and more with time? Isn't there any way to compress
the range? It seems strange to me, considering that an example in the book
suggests to use the document id as an array index for an array of maxDoc
elements.

Cheers,

Why wouldn't numdocs serve?
