--------------------------------------------------------

Everyone working on this patch should check out
http://lucene.zones.apache.org:8080/hudson/job/Lucene-Nightly/javadoc/org/apache/lucene/search/ParallelMultiSearcher.html
and make sure no work is being duplicated. My company is using 
'ParallelMultiSearcher' in a production environment with great success, so I 
wanted to make sure it is on everyone's radar.

Thanks!

> I experimentally implemented RemoteSearchable of Lucene for Solr.
> I referred to "FederatedSearch" and used RMI. 
> Two or more Searchers can be referred to with SolrIndexSearcher.
> These query-only indexes can be specified in solrconfig.xml, 
> enumerating the list under a <searchIndex> tag.
>   <searchIndex>
>     <lst>E:\sample\data1</lst>
>     <lst>E:\sample\data2</lst>
>     <lst>rmi://localhost</lst>
>   </searchIndex>
> The index in the dataDir is also used as the default index of solr
> to update and query.
> When data of a document in a index specified under the <searchIndex> is
> updated, 
> that document data in the index will be deleted and data of the updated 
> document will be stored
> in the index in the dataDir.
> SolrRemoteSearchable (the searcher for remote access) is started from 
> SolrCore 
> by specifying "< remoteSearcher>true</remoteSearcher >" in solrconfig.xml.(It 
> is registered in RMI. )
> ("-Djava.security.policy" should be set when you start VM. )
> Not all of the operational cases are tested 
> because Solr has so many features. 
> Moreover, TestUnit has not been made 
> because I made this through a trial and error process. 
> Some changes are required in Lucene to execute this. 
> I need your comments on this although it might be hard without TestUnit. 
> I especially worry about the followings: 
> - Am I on the right truck about this issue?
> - Is the extent of modifying Lucene tolerable?
> - Are there any ideas to implement this feature without modifying Lucene?
> - Does this idea contribute for improving Solr?
> - This implementation may partially overlap with "Multiple Solr Cores".
>   What should be done?
> - Are there any other considerations about this issue, which I have 
> overlooked?
