FW: Minor mistake on the Wiki

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.

Perhaps it could be worded better, but there is some sense behind it.
There is no document boost in a lucene lindex... a doc boost is simply
multipled into the boost for each field as the document is indexed.
