Server Weighting and Field Collapsing


(ppearcy) #1

Hello,
I've been very impressed with what I've seen so far with ES and was
curious if a couple of features were available or planned.

  1. Ability to weight servers in the cluster to receive different
    loads. Our newer h/w always seems to be 2x faster than older h/w and
    we'd like it to receive that load when placed into the cluster.

  2. Ability to collapse on a field. For example, I want the most
    relevant result from all different report types. Or similarly, the
    most recent result of each report type. So, the sort order would
    dictate which one from the group is returned. Similar to what is
    discussed here:
    http://blog.jteam.nl/2009/10/20/result-grouping-field-collapsing-with-solr/

From my understanding, it seems that in order for field collapsing to
be efficient, the result set must be relatively small.

Thanks,
Paul

Agreed on both features, both are something that I want to tackle for
elasticsearch. Open issues for them?

Great, thanks!


I'd be happy to provide any input you'd like.
