Acts as ferret, make index in /tmp then copy back to avoid N

Hi,

We’re happily using Ferret through acts_as_ferret on a Rails website,
but we have an issue with rebuilding indexes.

The Rails project directories are on an NFS mounted volume and
running Model.rebuld_index there seems to take 60-100 times longer
than it does on a local filesystem (e.g. /tmp).

What we’d like to do is rebuild our indexes in say /tmp, then copy
them back when done to the NFS volume with the Rails directories.

Is there any simple way to get Model.rebuild_index to build indexes
in a different place, or do we need to take another approach?

Thanks in advance,

Stu

If you use the DRb server it would be relatively easy since that (at
least in svn trunk) does index rebuilds in a separate directory
independent from the current index that is in use for searching.

By default the rebuild directory is named
RAILS_ROOT/index/class_name/rebuild
should be relatively easy to hack or even make this a configuration
option.
