In the page http://wiki.apache.org/solr/UpdateXmlMessages
We find:
Optional attributes on "doc"
* boost = <float> - default is 1.0 (See Lucene docs for
definition of boost.)
* NOTE: make sure norms are enabled (omitNorms="false"
in the schema.xml) for any fields where the index-time boost should be
stored.
This NOTE appears to be block-copied from the following entry about
field-level boosts, and makes no sense here.
