Solr Core Name Prefix

[Peter]

Hello,

If I want to connect single Solr instance with multiple DSpace instances, there is a setting to prefix Solr core:

solr.multicorePrefix = xyz

But how does it translate into folder structure for the cores? Should they be placed in subfolders within, e.g., [solr]/server/solr/configsets, with subfolder name reflecting "solr.multicorePrefix"?

Do not quite understand this setting.

Thanks

Peter

For those who might need it:

Setting

solr.multicorePrefix = folder_name_

should reflect core prefixes (which reside, e.g., in [solr]/server/solr/configsets), like:

folder_name_authority

folder_name_oai

folder_name_qaevent

etc.

I find it helpful to collect the set of cores for each DSpace instance
in a separate folder, but it isn't necessary.

As you have found, the multicore prefix will be pre-pended to the name
of that instance's core folders, so in your original example the cores
will be in [solr]/server/solr/configsets/xyzauthority, xyzoai,
xyzsearch, xyzstatistics.

If you use sub-folders, the names don't matter to Solr. Name them in
a way that is easy for you to associate with their DSpace instances,
or whatever works for you. I name them by the multicorePrefix,
without any trailing separator such as "_".

Solr will search $SOLR_HOME ([solr]/server/solr in your example) and
its sub-folders for folders containing a file named 'core.properties'
(which can be empty). Any such folder will be loaded as a core, and
the simple name of the folder will be the name of the core.
