forget about the default setup that comes w/ the example. say you have the following structure /data/solr/home/ solr.xml conf/ schema.xml solrconfig.xml data/ /c1/ index /c2/ index /c3/ index
* your solr.solr.home is /data/solr/home * your common instanceDir will be /data/solr/home/ again. pass this parameter whenever you create a new core. * the conf dir contains the common files required for each core. * in your common solrconfig.xml keep a tag <dataDir>/data/solr/home/data/${solr.core.name}</dataDir> .(my previous mail had a mistake *assume your core names are c1,c2,c3 then solr will automatically create a structure as described above. (no need to create the dirs c1 or c2 or c3) HTH On Tue, May 19, 2009 at 4:28 PM, KK <dioxide.softw...@gmail.com> wrote: > Thanks Paul. > > But I'm a bit confused.
