			Binary extraction example. This needs to be configured in two places:
				1. solrconfig.xml: 
					map binary content to a binary field and for instance
					map the title extracted from the binary to a BinaryEmbeddedTitle field
					An example is:
						<requestHandler name="/update/extract" class="org.apache.solr.handler.extraction.ExtractingRequestHandler">
						<lst name="defaults">
						<str name="uprefix">binary_</str>
						<str name="fmap.content">binary_content</str>
						<str name="fmap.title">BinaryEmbeddedTitle</str>
						</lst>
						</requestHandler>
				2. schema.xml:
					create fields for the mapped field types in step 1.
