Subject Solr for multiple websites
Date Mon, 16 Aug 2010 16:13:54 GMT

We have a news portal built on a CMS that heavily uses solr for indexing.
Going ahead we will be migrating all our other portals to the same platform
and are not sure how do we work with Solr for multiple websites.

The options are:

1) Using multiple publications/indexes within solr for each site
2) Run one instance/schema of solr for all websites

The advantage of (1) is all websites will not be affected if there is
something wrong with one solr publication, the downside being sharing of
content between multiple websites.
While the (2) does provide you with flexibility of sharing/searching content
across multiple websites but also comes with the risk of adding all websites
to a single schema (which may cause performance issues).

Would appreciate if someone can guide us in the right direction and share
their experience with us.
