The Distributed Search feature has nothing to do with the MultiCore feature. <http://wiki.apache.org/solr/DistributedSearch> http://wiki.apache.org/solr/DistributedSearch Distributed Search is a "horizontal partition" on an index schema, meaning there are multiple indexes supplying different records with the same schema. Using different schemas with a common primary key is called a "vertical partition". http://en.wikipedia.org/wiki/Partition_(database) http://windowsitpro.com/article/articleid/98/horizontal-and-vertical-partiti oning.html http://manuals.sybase.com/onlinebooks/group-asarc/asg1200e/aseperf/@Generic_ _BookTextView/1377 The Sybase manual has the pictures that really explain the terms "horizontal" and "vertical".

I attached an example for you. The challenge with MultiCore is on the client's search logic. It would help if you know which language the person wants to search through. If not you would have to perform multiple requests to the multiple cores. Ordinary logic would be: 1. search "chien" in core0 (english) 2. if #1 returned zero results search for "chien" in core1 (french) --- In your client you could even parallelize the requests to minimize waiting time. One feature I didn't try yet is the DistributedSearch (and how it will help with multiple cores), find it here: http://wiki.apache.org/solr/DistributedSearch Regards, Hannes On Tue, Oct 14, 2008 at 4:26 PM, sunnyfr <[EMAIL PROTECTED]> wrote: Thanks for this explanation, but just to get it properly : One core per language, so with the same field and schema just the language part and management which is different? and one core which consider every language which are not managed by solr like russian or ??? so different request to the dabase.... ok Just don't get really when you look for the word 'chien' on the english website I want get back result from french video because chien is french so if it doesn't find any english video with chien I need my french video then. Exactly the same for user's core, if somebody look for 'chien' and there is one user with exactly the same username I would like to show it up. thanks for your time, really, John E.
