Obviously we could, but it wouldn't help in the common case where the
database is opened afresh by each search process.

One approach (rather a long term one) is to allow arbitrary docids -
then searching over multiple databases can simple prefix the docids from
each.  Probably the main challenge there is to maintain the ability to
store them compactly.
