- This schema is not minimal, there are some useful field type definitions left,
- and the set of fields and their flags (indexed/stored/term vectors) can be
- further optimized depending on needs. See
- http://svn.apache.org/viewvc/lucene/dev/trunk/solr/example/solr/conf/schema.xml?view=markup
- for more info.
