Re: multicore vs multi collection
Does that means i can create multiple collections with different configurations ? can you please outline basic steps to create multiple collections,cause i am not able to create them on solr 4.0 -- View this message in context: http://lucene.472066.n3.nabble.com/multicore-vs-multi-collection-tp4051352p4052002.html Sent from the Solr - User mailing list archive at Nabble.com.
Re: multicore vs multi collection
Unable? In what way? Did you look at the Solr example? Did you look at solr.xml? Did you see the core element? (Needs to be one per core/collection.) Did you see the multicore directory in the example? Did you look at the solr.xml file in multicore? Did you see how there are separate directories for each collection/core in multicore? Did you see how there is a core element in solr.xml in multicore, one for each collection directory (instance)? Did you try setting up your own test directory parallel to multicore in example? Did you read the README.txt files in the Solr example directories? Did you see the command to start Solr with a specific Solr home directory? - java -Dsolr.solr.home=multicore -jar start.jar Did you try that for your own test solr home directory created above? So... what exactly was the problem you were encountering? Be specific. My guess is that you simply need to re-read the README.txt files more carefully in the Solr example directories. If you have questions about what the README.txt files say, please ask them, but please be specific. -- Jack Krupansky -Original Message- From: hupadhyay Sent: Thursday, March 28, 2013 5:35 AM To: solr-user@lucene.apache.org Subject: Re: multicore vs multi collection Does that means i can create multiple collections with different configurations ? can you please outline basic steps to create multiple collections,cause i am not able to create them on solr 4.0 -- View this message in context: http://lucene.472066.n3.nabble.com/multicore-vs-multi-collection-tp4051352p4052002.html Sent from the Solr - User mailing list archive at Nabble.com.
Re: multicore vs multi collection
Did you check that document: http://wiki.apache.org/solr/SolrCloud#A_little_about_SolrCores_and_CollectionsIt says: On a single instance, Solr has something called a SolrCorehttp://wiki.apache.org/solr/SolrCorethat is essentially a single index. If you want multiple indexes, you create multiple SolrCores http://wiki.apache.org/solr/SolrCores. With SolrCloud, a single index can span multiple Solr instances. This means that a single index can be made up of multiple SolrCorehttp://wiki.apache.org/solr/SolrCore's on different machines. We call all of these SolrCoreshttp://wiki.apache.org/solr/SolrCoresthat make up one logical index a collection. A collection is a essentially a single index that spans many SolrCorehttp://wiki.apache.org/solr/SolrCore's, both for index scaling as well as redundancy. If you wanted to move your 2 SolrCore http://wiki.apache.org/solr/SolrCore Solr setup to SolrCloud, you would have 2 collections, each made up of multiple individual SolrCoreshttp://wiki.apache.org/solr/SolrCores. 2013/3/26 J Mohamed Zahoor zah...@indix.com Hi I am kind of confuzed between multi core and multi collection. Docs dont seem to clarify this.. can someone enlighten me what is ther difference between a core and a collection? Are they same? ./zahoor
Re: multicore vs multi collection
Thanks. This make it clear than the wiki. How do you create multiple collection which can have different schema? ./zahoor On 26-Mar-2013, at 3:52 PM, Furkan KAMACI furkankam...@gmail.com wrote: Did you check that document: http://wiki.apache.org/solr/SolrCloud#A_little_about_SolrCores_and_CollectionsIt says: On a single instance, Solr has something called a SolrCorehttp://wiki.apache.org/solr/SolrCorethat is essentially a single index.

Re: multicore vs multi collection
Also from there http://wiki.apache.org/solr/SolrCloud: *Q:* What is the difference between a Collection and a SolrCorehttp://wiki.apache.org/solr/SolrCore? *A:* In classic single node Solr, a SolrCorehttp://wiki.apache.org/solr/SolrCoreis basically equivalent to a Collection. It presents one logical index. In SolrCloud, the SolrCore http://wiki.apache.org/solr/SolrCore's on multiple nodes form a Collection. This is still just one logical index, but multiple SolrCores http://wiki.apache.org/solr/SolrCores host different 'shards' of the full collection. So a SolrCorehttp://wiki.apache.org/solr/SolrCoreencapsulates a single physical index on an instance. A Collection is a combination of all of the SolrCores http://wiki.apache.org/solr/SolrCoresthat together provide a logical index that is distributed across many nodes. 2013/3/26 J Mohamed Zahoor zah...@indix.com Thanks.
