["Ryan McKinley (Updated) (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/SOLR-3134?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Ryan McKinley updated SOLR-3134:
--------------------------------

    Attachment: SOLR-3134-shard-info.patch

This patch addes two parameters:

{code:java}
  /** Request detailed match info for each shard (true/false) */
  public static final String SHARDS_INFO = "shards.info";

  /** Should things fail if there is an error? (true/false) */
  public static final String SHARDS_TOLERANT = "shards.tolerant";
{code}

When 'shards.info=true', it adds adds a node to the response:
{code:xml}
<lst name="shards.info">
  <lst name="localhost:7777/solr">
    <long name="numFound">1333</long>
    <float name="maxScore">1.0</float>
    <long name="time">686</long>
  </lst>
  <lst name="localhost:8888/solr">
    <long name="numFound">342</long>
    <float name="maxScore">1.0</float>
    <long name="time">602</long>
  </lst>
</lst>
{code}

When 'shards.tolerant=true' it does not abort when a request has an error.  If 'shards.info=true', it will add error info to the response for that shard, like:

{code:xml}
<lst name="shards.info">
  <lst name="badurl:3456/solr">
    <str name="error">java.net.UnknownHostException: badurl</str>
    <str name="trace">java.net.UnknownHostException: badurl

> For distributed search where each shard represents a logically different index (or physical location), it would be great to know the hit count for each shard.
> In addition, it would be nice to get error info for each shard rather then aborting the whole request when something fails.
