- This is the Solr schema file. This file should be named "schema.xml" and
- should be in the conf directory under the solr home
- (i.e. ./solr/conf/schema.xml by default) 
- or located where the classloader for the Solr webapp can find it.
-
- This example schema is the recommended starting point for users.
- It should be kept correct and concise, usable out-of-the-box.
-
- For more information, on how to customize this file, please see
- http://wiki.apache.org/solr/SchemaXml
-
- PERFORMANCE NOTE: this schema includes many optional features and should not
- be used for benchmarking.  To improve performance one could
-  - set stored="false" for all fields possible (esp large fields) when you
-    only need to search on the field but don't need to return the original
-    value.
-  - set indexed="false" if you don't need to search on the field, but only
-    return the field as a result of searching on other indexed fields.
-  - remove all unneeded copyField statements
-  - for best index size and searching performance, set "index" to false
-    for all general text fields, use copyField to copy them to the
-    catchall "text" field, and use that for searching.
-  - For maximum indexing performance, use the StreamingUpdateSolrServer
-    java client.
-  - Remember to run the JVM in server mode, and use a higher logging level
-    that avoids logging every request
