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)
