Subject [jira] [Commented] (SOLR-6311) SearchHandler should use path when no qt or shard.qt parameter is specified
Date Wed, 11 Feb 2015 16:40:14 GMT

    [ https://issues.apache.org/jira/browse/SOLR-6311?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14316493#comment-14316493

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.

> 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.
