            <b>Search results</b> are displayed by concept preferred name. 
            If you are searching multiple sources, a right-hand column
            displays the source of each matching concept.  If there is
            only one match, the concept details page is shown directly
            without first listing results, unless the matching concept
            is in the NCI Metathesaurus (because this links to the
            separate NCIm Browser). Some details: 
            <ul>
              <li>All matching concepts are returned.</li>
              <li>Results are listed from best match to weakest. For
  
negative.code:               the top, followed by concepts with two word matches
                (e.g., <i>Flat Bone</i>), followed by concepts whose terms
                have more non-<i>Bone</i> content. Ranking of results from
                multiple sources is still uneven, so that, e.g.,
                exact matches from one source may appear after some
                weaker matches from other sources; we are working
                to fix this problem.</li>
              <li>The match will often be to synonyms or codes only
                visible on the concept details page (e.g., searching
                <b>Begins With</b> <font face="courier">melanoma</font> will show <i>Corneal Melanoma</i> in
                the results list because that concept contains a
                synonym of <i>Melanoma of the Cornea</i>.) A future release
                will show these matches in the results window.</li>
