after the initial index finishes an announcement is shown to that effect,
and from then on it remains suspended. i also believe that nepomuk is
monitoring file changes to keep things up-to-date, but haven't seen an
explanation of that in any blog or mailing list post yet; was hoping to
find here somebody who actually knows.
moreover, after the initial index finished i un-suspended file indexing
manually, and nepomuk/strigi apparently did find new areas (directories)
that are also within the specified search area, but haven't been indexed
during the first run, adding a couple hundred files to the search index
and MB to the nepomuk data store -- which probably wouldn't have happened
if i hadn't un-suspended file indexing manually.
seems file indexing is being suspended as soon as possible to prevent
people from complaining that nepomuk eats all their CPU cycles. perhaps
that still needs some work, to manage nepomuk's re-emergence once in a
while to make sure it got everything indexed it's supposed to.
