That's actually the expected behavior currently.

It used to be that "notmuch search" on the command line wouldn't present
any results until everything was available.

I recently threw in a hack to present the first 100 thread results
quickly and only then does it sit and spin before all the results are
available. I suppose it wouldn't be any harder for it to keep returning
chunks of 100 threads at a time, (though this will slow down the final
result a bit---perhaps not significantly).

And I wouldn't really mind any slowdown there anyway, since any *real*
interface should be calling "notmuch search" in small chunks anyway.

So I'll go ahead and do that.

I don't think the bogus dates are throwing anything off. It's more
likely that you just have a number of messages with no Date header on
them at all. And for such messages, notmuch just chooses a time_t value
of 0 so you'll see whatever that 0 maps to on your system---a date of
1970 there is not surprising. :-)

See my other mail. You may want to tweak the behavior of "notmuch new"
before running it again. (I would not expect the results to be any
different from running it again with no change.)
