[jira] Commented: (SOLR-1506) Search multiple cores using MultiReader

["Jason Rutherglen (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SOLR-1506?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12789600#action_12789600 ] 

Jason Rutherglen commented on SOLR-1506:
----------------------------------------

There's a different bug here, where because CoreContainer loads
the cores sequentially, and MultiCoreReaderFactory looks for all
the cores, when the proxy core isn't last, not all the cores are
searchable, if the proxy is first, an exception is thrown. 

The workaround is to place the proxy core last, however that's
not possible when using the core admin HTTP API. Hmm... Not sure
what the best workaround is.

> I need to search over multiple cores, and SOLR-1477 is more
> complicated than expected, so here we'll create a MultiReader
> over the cores to allow searching on them.
> Maybe in the future we can add parallel searching however
> SOLR-1477, if it gets completed, provides that out of the box.
