Hoss Man commented on SOLR-6311:
--------------------------------
bq. It should have been done this way to begin with. I consider it a bug that
distributed requests were apparently hard-coded to use /select
Definitely not a bug.
you have to remember the context of how distributed search was added -- prior
to SolrCloud, you had to specify a "shards" param listing all of the cores you
wanted to do a distributed search over, and the primary convinience mechanism
for doing that was to register a handler like this...
{noformat}
<requestHandler name="/my_handler" class="solr.SearchHandler"/>
<lst name="defaults">
<str name="shards">foo:8983/solr,bar:8983/solr</str>
<int name="rows">100</int>
</lst>
</requestHandler>
{noformat}
...so the choice to have "shards.qt" default to "/select" instead of the
current qt was _extremely_ important to make distributed search function
correctly for most users for multiple reasons:
1) so that the shards param wouldn't cause infinite recursion
2) so that the "defaults" wouldn't be automatically inherited by the per-shard
requests
But now is not then -- the default behavior of shards.qt should change to make
the most sense given the features and best practice currently available in
Solr. SolrCloud solves #1, and IIUC useParams solves #2, so we can move
forward.
> SearchHandler should use path when no qt or shard.qt parameter is specified

>
> When performing distributed searches, you have to specify shards.qt unless
> you're on the default /select path for your handler. As this is configurable,
> even the default search handler could be on another path. The shard requests
> should thus default to the path if no shards.qt was specified.
