               <ul>
                 <li>All matching concepts are returned.</li> 
  +              <li>Results are listed from best match to weakest. For example, a Contains search on Bone returns <i>Bone</i> at the top, followed by concepts with two word matches (e.g., <i>Flat Bone</i>), followed by concepts whose terms have more non-Bone content.</li>
                 <li>The match will often be to synonyms or codes only visible on the concept details page (e.g., searching Begins With melanoma 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>
                 <li>If there are too many to show on one page, you can page through the results with a default of 50 per page. To change the default number, use the Show results per page drop-down menu at the bottom of the results page.</li>
                 <li>In the next release, concepts whose status is unusual (e.g., retired or obsolete) will show their status in parentheses in the results listing.</li>

            <b>In the Search box</b>, enter all or part of what you are looking for and click the "Search" button. Some details:
            <ul>
              <li>You can search for a concepts preferred name, synonyms, acronyms, or codes.
              <li>"Exact Match" is the default: Only terms or codes that are identical will match.
              <li>"Begins With" can be selected to find all terms or codes that start with the words or characters you enter.
              <li>"Contains" will search for what you enter anywhere within a term or code (e.g., "carcinoma" will match <i>adenocarcinoma</i>).
              <li>Search is not case sensitive (e.g., aids will match <i>aids</i>, <i>Aids</i>, and <i>AIDS</i>).
              <li>There are no wildcard characters.  All characters are matched literally (e.g., using "Begins With", NAT2* will match <i>NAT2*5 Allele</i> but not <i>NAT2 Gene</i>).
              <li>Searching for multiple words does not search on each word separately.  To match, all words have to be found in the same order you provided.  For example, if you do a Contains search on Melanoma Corneal, no results will be returned.  But if you search on Corneal Melanoma, you get the detail page for Corneal Melanoma.</li>

            <ul>
              <li>Some searches returning thousands of results hit internal limits in the LexEVS 4.2/LexBIG 2.3 server.  The browser detects this failure and falls back to a safe search that will return only some of the matching concepts (only full-word matches, normally the best), warning the user about the problem.  This problem should be fixed with the LexEVS 5.0 release in June 2009.</li>
              <li>The default scoring for search matches will continue to be improved, and some user-settable options should be part of the forthcoming Advanced Search page.</li>
              <li>Online and standalone documentation are still under development.</li>
