Noble Paul commented on SOLR-2592:
----------------------------------
This is why I created the issue SOLR-1431 . It may have a configuration as
follows
{code:xml}
<requestHandler name="standard" class="solr.SearchHandler" default="true">
<!-- other params go here -->
<shardHandler class="CloudShardHandler"/>
</requestHandler>
{code}
The CloudShardHandler should lookup ZK and return all the shards return all the
shards by default.
I should be able to write a custom FqFilterCloudShardHandler and narrow down
the requests to one or more shards
{code:xml}
<requestHandler name="standard" class="solr.SearchHandler" default="true">
<!-- other params go here -->
<shardHandler class="FqFilterCloudShardHandler"/>
</requestHandler>
{code}

> If the data in a cloud can be partitioned on some criteria (say range, hash,
> attribute value etc) It will be easy to narrow down the search to a smaller
> subset of shards and in effect can achieve more efficient search.
