: Is it possible to duplicate a core? I want to have one core contain only
: documents within a certain date range (ex: 3 days old), and one core with
: all documents that have ever been in the first core. The small core is then
: replicated to other servers which do real-time processing on it, but the
: archive core exists for longer term searching.
It's not something i've ever dealt with, but if i were going to pursue it
i would investigate wether this works...
1) have three+ solr instances: master, archive and one or more query
machines
2) index everything to core named recent on server master
3) configure the query machines to replicate recent from master
4) configure the archive machine to replicate recent from master
5) configure the archive machine to also have an all core
6) on some timed bases:
- delete docs from recent on master that are *older* then X
- delete docs from recent on archive that are *newer* then X
- use the index merge command on archive to merge the recent
core into the all core
...i'm pretty sure that merge command will require that you shutdown both
cores on archive during the merge, but that's a good idea anyway.
if you need continuous searching of the all core to be available, then
just setup that core on archive as a repeater and have some
archive-query machines slaving off of it.
that should work.
