This is great,
What file do I need to edit?  Just the search.jsp or what.

Andy,

I am using this tag
library:  http://jsptags.com/tags/navigation/pager/index.jsp

You will have to hack the program a little and make sure to pass the
correct variables.  See basic example below:

Neal


<%-- PAGER OPTIONS --%>
<%
     String style = getParam(request, "style", "alltheweb");
     String position = getParam(request, "position", "top");
     String index = getParam(request, "index", "center");
     //int maxPageItems = getParam(request, "maxPageItems", 15);
     int maxPageItems = hitsPerPage;
     int maxIndexPages = getParam(request, "maxIndexPages", 9);

     int myCount = (int)hits.getTotal();  //big total max results this
changes a long value to an int value???
%>


Also: changed the startString from "start" variable to "pager.offset".

//  String startString = request.getParameter("start");
     String startString = request.getParameter("pager.offset");






<%-- START PAGINATION --%>


<%
//Check to see how far in the pagination you are.
if ((hits.totalIsExact() && end < hits.getTotal()) // more hits to show
     || (!hits.totalIsExact() && (hits.getLength() >
start+hitsPerPage)))
    {
%>




<%
//Reset some variables
String hitsPerPage2 = request.getParameter("hitsPerPage");
String hitsPerSite2 = request.getParameter("hitsPerSite");
%>


<pg:pager
     items="<%= myCount %>"
     index="<%= index %>"
     maxPageItems="<%= maxPageItems %>"
     maxIndexPages="<%= maxIndexPages %>"
     isOffset="<%= true %>"
     export="offset,currentPageNumber=pageNumber"
     url="http://www.yourdomain.com:8080/search.jsp";
     scope="request">

   <pg:param name="query" value="<%= queryString %>"/>
   <pg:param name="hitsPerPage" value="<%= hitsPerPage2 %>"/>
   <pg:param name="hitsPerSite" value="<%= hitsPerSite2 %>"/>
   <pg:param name="clustering" value="<%= clustering %>"/>



<%-- keep track of preference --%>
   <pg:param name="style"/>
   <pg:param name="position"/>
   <pg:param name="index"/>
   <pg:param name="maxPageItems"/>
   <pg:param name="maxIndexPages"/>



   <%-- save pager offset during form changes --%>



   <%-- warn if offset is not a multiple of maxPageItems --%>
   <% if (offset.intValue() % maxPageItems != 0 &&
          ("alltheweb".equals(style) || "lycos".equals(style)) )
      {
   %>
     <p>Warning: The current page offset is not a multiple of Max. Page
Items.
     <br>Please
     <pg:first><a href="<%= pageUrl %>">return to the first
page</a></pg:first>
     if any displayed range numbers appear incorrect.</p>
   <% } %>

   <%-- the pg:pager items attribute must be set to the total number of
        items for index before items to work properly --%>
   <% if ("top".equals(position) || "both".equals(position)) { %>
     <br>
     <pg:index>
       <% if ("texticon".equals(style)) { %>
         <jsp:include page="/WEB-INF/jsp/texticon.jsp" flush="true"/>
       <% } else if ("jsptags".equals(style)) { %>
         <jsp:include page="/WEB-INF/jsp/jsptags.jsp" flush="true"/>
       <% } else if ("google".equals(style)) { %>
         <jsp:include page="/WEB-INF/jsp/google.jsp" flush="true"/>
       <% } else if ("altavista".equals(style)) { %>
         <jsp:include page="/WEB-INF/jsp/altavista.jsp" flush="true"/>
       <% } else if ("lycos".equals(style)) { %>
         <jsp:include page="/WEB-INF/jsp/lycos.jsp" flush="true"/>
       <% } else if ("yahoo".equals(style)) { %>
         <jsp:include page="/WEB-INF/jsp/yahoo.jsp" flush="true"/>
       <% } else if ("alltheweb".equals(style)) { %>
         <jsp:include page="/WEB-INF/jsp/alltheweb.jsp" flush="true"/>
       <% } else { %>
         <jsp:include page="/WEB-INF/jsp/simple.jsp" flush="true"/>
       <% } %>
     </pg:index>
   <% } %>


You can put content here or just place this code block at the bottom 
of your page.



<% if ("bottom".equals(position) || "both".equals(position)) { %>
   <pg:index>
     <% if ("texticon".equals(style)) { %>
         <jsp:include page="/WEB-INF/jsp/texticon.jsp" flush="true"/>
     <% } else if ("jsptags".equals(style)) { %>
         <jsp:include page="/WEB-INF/jsp/jsptags.jsp" flush="true"/>
     <% } else if ("google".equals(style)) { %>
         <jsp:include page="/WEB-INF/jsp/google.jsp" flush="true"/>
     <% } else if ("altavista".equals(style)) { %>
         <jsp:include page="/WEB-INF/jsp/altavista.jsp" flush="true"/>
     <% } else if ("lycos".equals(style)) { %>
         <jsp:include page="/WEB-INF/jsp/lycos.jsp" flush="true"/>
     <% } else if ("yahoo".equals(style)) { %>
         <jsp:include page="/WEB-INF/jsp/yahoo.jsp" flush="true"/>
     <% } else if ("alltheweb".equals(style)) { %>
         <jsp:include page="/WEB-INF/jsp/alltheweb.jsp" flush="true"/>
     <% } else { %>
         <jsp:include page="/WEB-INF/jsp/simple.jsp" flush="true"/>
     <% } %>
   </pg:index>
<% } %>
</pg:pager>


<%
     }
%>

<%-- END PAGINATION --%>
