Sharad Agarwal commented on SOLR-255:
-------------------------------------
Toru, Along with the query processing, RequestHandlers also add more info to
response, like 'highlighting' and 'moreLikeThis' information. I am not clear
how this get accomplished in the distributed environment?
Collecting Highlighting info for all top N records from all shards could be
quite expensive. How about first combining the results from shards and then
gathering Highlighting info?
> RemoteSearchable for Solr(use RMI)

> Key: SOLR-255
> URL: https://issues.apache.org/jira/browse/SOLR-255
> Project: Solr
> Issue Type: Improvement
> Components: search

>
> 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?
