Helpful hints on Large Solr Indexes and Schema Design

Solr user Lance Norskog has been kind enough to contribute documentation on:

• Common Solr Schema Design problems and solutions
• Design considerations for Unique Keys for common use-cases
• Common problems and solutions for Large Solr Indexes

Very useful documentation which, no doubt, will be made more comprehensive with time.

Update - Mark Miller has written a very nice article on Scaling Lucene and Solr at the Lucid Imagination website.
