May I ask: how to set up multiple indexes, and specify which index to send
the docs to at indexing time, and later on, how to specify which index to
work with?
A related question: what is the storage location and structure of solr
indexes?
When you index or query data, you'll use a base URL specific to the
index (core). Everything goes through that base URL, which includes the
name of the core:
http://server:port/solr/corename
The file called solr.xml tells Solr about multiple cores.Each core has
an instanceDir and a dataDir.
http://wiki.apache.org/solr/CoreAdmin
In the dataDir, Solr will create an index dir, which contains the Lucene
index. Here are the file formats for recent versions:
http://lucene.apache.org/core/4_0_0/core/org/apache/lucene/codecs/lucene40/package-summary.html
http://lucene.apache.org/core/3_6_1/fileformats.html
http://lucene.apache.org/core/old_versioned_docs/versions/3_5_0/fileformats.html
