anchor.diff:              <li><b>Begins With</b> can be selected to find all terms or codes that start with the words or characters you enter.
               <li><b>Contains</b> will search for what you enter anywhere within a term or code (e.g.,
               <i>carcinoma</i> will match <i>adenocarcinoma</i>).
  +            <li><b>Rank (Slow)</b> sorts results from best match to weakest if the check box is selected.  For example, a <b>Contains</b>
  +            search on <i>melanocyte</i> returns <i>melanocyte</i> at the top, followed by concepts with two word matches (e.g.,
  +            <i>Spindle Melanocyte</i>), followed by concepts whose terms have more non-<i>melanocyte</i> content.It is off by
  +            default due to poor performance.
               <li>Concept Unique Identifiers (CUIs) and codes from individual sources will only match if they exactly match what you enter, even if you select <b>Begins With</b> or <b>Contains</b>.
               <li>Search is not case sensitive (e.g., aids will match <i>aids</i>,
               <i>Aids</i>, and <i>AIDS</i>).
  
positive.code:               <li><b>Relationships</b>: Shows how other concepts are directly related to this concept as parents, children,
                or in other ways.
                <li><b>Synonym Details</b>: For each term or abbreviation, shows its source, term type, and code.
                <li><b>By Source</b>: Shows concept information one source at a time. NCI Thesaurus content is shown if available, otherwise the initial source is chosen alphabetically. To view concepts by a different source, select on the link for that source at the top of the page. NOTE: Select the ? icon next to the Source header to view a list of the source abbreviations and full names.
                <li><b>View All</b>: Combines all of the above information on a single page.
              </ul>
              <li><b>In NCIt Hierarchy</b>: Click the button to see where the concept is found within the NCIt hierarchy as

            There are important known issues in data, functionality and documentation that we are working to address for release 2.
            These include the following:
            <ul>
              <li><b>Data</b>: NCI Metathesaurus data were significantly abbreviated in the LexEVS 5.0 implementation. Of particular
              importance,
              <ul>
                <li>Relationship data are not consistently stored and linked, and are represented incompletely as described in the
                browsers <a href="<%= request.getContextPath() %>/pages/rela_help_info.jsf">Relationship Attribute Help</a>.
                This also made it impossible to reliably display individual source hierarchies within their broader NCIm context.
                <li>Other source specific concept data were also only partly loaded.
              </ul>
              <br>These problems should be fixed with the LexEVS 5.1 release in late 2009.<br><br>
              <li><b>Functionality</b>: Performance problems have been partly designed around but are still an important issue that
              we intend to fix.  The ranking of search results best matches first could not achieve acceptable performance and was
              made a user option with warning attached.  The Relationship and By Source tabs are also too slow. User-settable options
              and the ability to search other concept data and relationships are needed, and should be part of forthcoming browser
              releases.
              <li><b>Documentation</b>: Online and standalone documentation are still under development.
            </ul>
