How to handle updates from other machine

Ruby Apps Ferret
1

Hi,
Right now I’m having ferret index about 1.5million documents. I plan on
rebuilding the index on another machine and then copying the index over
to the webserver. I read in one of the other posts that ferret has to
reopen the index to see any new changes. Is there a way to script this?
My frontend is a RoR app using AAF.
Thanks,
Chris

A related question (apologies to Chris for jumping in on his question):

Are there any issues we should be aware of when copying indexes between
machines? Like, can we copy to and from any pair of machines? Or are
there
binary layout/word size/Endian issues?

you could build a ‘secret’ action in your app that triggers the
reopening of the index.

Or you check if your reader is reading from the current index before
using it with IndexReader#is_latest?

I see. Doesn’t AAF just reopen the index again on the next request
though? I don’t mind if updates aren’t seen until the next request
occurs…

Right, aaf uses Ferret’s Ferret::I class which afair does check if
it’s searcher looks at the most recent version of the index, so
everything should be fine.
