Yonik Seeley commented on SOLR-705:
-----------------------------------
bq. interesting. What defines a 'slice'? Could it be a system property, or
something in SolrConfig?
It's well defined within SolrCloud... you can actually add
&shards=shard1,shard2 and solr will do the mapping from those logical shards to
physical shards (via cluster state in zookeeper) and do a load-balanced request
across them.
> Distributed search should optionally return docID->shard map

> SOLR-303 queries with &shards parameters set need to return the dociD->shard
> mapping in the response. Without it, updating/deleting documents when the #
> of shards is variable is hard. We currently set this with a special
> requestHandler that filters /update and inserts the shard as a field in the
> index but it would be better if the shard location came back in the query
> response outside of the index.
