  +          Many sources have hierarchies of concepts, arranged from the most general at the top to the most
  +          specific at the bottom leaf nodes. Most common are "is-a" hierarchies, where child concepts are
  +          subtypes of their parent(s) (e.g., Mold is-a Fungus), but other relationships, such as "part-of",
  +          are also used by some source terminologies. The browser provides several ways of viewing hierarchies
  +          when they are available.

            This release, based on LexEVS 5.1, addresses most known data and performance issues. We are still working on
            remaining issues of data, functionality and documentation, which include the following:
            <ul>
              <li><b>Data</b>: NCI Metathesaurus has a few remaining gaps in data, plus some issues of best interpretation and presentation. Of particular importance,
              <ul>
                <li>Relationship data are represented somewhat differently in different sources, and the summary labels, described in the browsers
                <a href="#" onclick="javascript:window.open('<%= request.getContextPath()%>/pages/rela_help_info.jsf',
                        '_blank','top=100, left=100, height=740, width=780, status=no, menubar=no, resizable=yes, scrollbars=yes, toolbar=no, location=no, directories=no');">
                Relationship Attribute Help</a>,
                sometimes appear to be inappropriate. This also complicates efforts to reliably display individual source hierarchies within their broader NCIm context.
                <li>The display of history data has been postponed until a future release.
                <li>Some additional categories of source specific concept data are not included, but are being considered for inclusion in future releases.
              </ul>
              <li><b>Functionality</b>: Performance has greatly improved, but has been partly offset by the several-fold increase in
              data.  Search results are ranked by goodness of match, but Contains searches had to be limited to the beginning or
              end of words to get good performance. There are still performance issues with the display of concepts having many
              thousands of relationships, and hierarchy display is still painfully 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.

            <b>In the Search box,</b>
            enter all or part of what you are looking for, set what and how you want to search, and click
            the <b>Search</b> button. Some details:
            <!-- ************* Search ************** -->
            <ul>
              <li><b>Text Box:</b> Enter the exact string of characters you want to search for.
              <ul>
                <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., searching
                for <b>Begins With</b> <span style="font-family:monospace;">NAT2*</span> will match <i>NAT2*5 Allele</i> but not <i>NAT2 Gene</i>).
                <li>Do not use quotes - they will be searched for literally, as characters to be matched.
                <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 <b>Contains</b>
                search on <span style="font-family:monospace;">Melanoma Corneal</span> no results will be returned, but if you search on
                <span style="font-family:monospace;">Corneal Melanoma</span> you get the detail page
                for <i>Corneal Melanoma</i>.
              </ul>
              <li><b>Match method radio buttons</b> select how your search string will be matched.
              <ul>
                <li><b>Exact Match</b> is the default: Only terms or codes that are identical will match.
                <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.,
                <span style="font-family:monospace;">carcinoma</span> will match <i>adenocarcinoma</i>).
                <li>Concept Codes will only match if they exactly match what you enter, even if you
                select <b>Begins With</b> or <b>Contains</b>.
              </ul>
              <li><b>Match target radio buttons</b> select what category of concept information is searched
              <ul>
                <li><b>Name/Code</b> is the default: Search text is matched to a concept's preferred name, synonyms, acronyms, or codes. Unless stated otherwise, all search examples in this Help page use the default name/code search.
                <li><b>Property</b> will match to other direct property attributes of a concept, such as definitions.
                <li><b>Relationship</b> will return concepts that have relationships to concepts that match
                by name/code (e.g., an exact relationship search on <span style="font-family:monospace;">toe</span>
                does not return the concept <i>toe</i>, but does return <i>toenail</i> and other related concepts).
              </ul>
              <li><b>Source</b> drop-down box: You can choose to limit your search to concepts with terms from
              a specific source. For example, if you only want to find <i>breast cancer</i> concepts that
              include terms from SNOMEDCT, you would choose <span style="font-family:monospace;">SNOMEDCT</span>
              from the <b>Source</b> box. This will return concepts with at least one SNOMDEDCT term and at
              least one term that matches your search criteria, even if the matching terms are not from the
              selected source. This search method is helpful for users looking for source coverage of a term
              that may be expressed differently in that source (e.g., searching for grey for source FDA will
              return <i>Gray color</i>, even though the only FDA term is the American spelling gray).
              <li><b>Source Hierarchy button</b> If you select a source with a concept hierarchy that can
              be viewed, an icon will appear to the right of the source selection box; click on the icon to
              view the hierarchy in a separate window.
              <li><b>Search</b> button starts a search.
              <li><b>"?"</b> button takes you to this Search section of the Help file.

            The key differences are:

              <li><b>Code</b> and <b>Name</b> are searched separately.
              <li><b>Property</b> search offers a drop down list of all specific properties in NCIm, so that
              they can be selected and searched individually.
              <li><b>Relationship</b> search offers drop down lists of broad relationship labels (RELs) and
              specific relationship attributes (RELAs) that can be searched on, as explained in the

              broader PAR (Parent) REL relationship.
