Correct. Simply install the library and edit search.jsp. You will
need to edit the web.xml file in the WEB-INF dirctory to include the taglib.
<taglib>
<taglib-uri>http://jsptags.com/tags/navigation/pager</taglib-uri>
<taglib-location>/WEB-INF/jsp/pager-taglib.tld</taglib-location>
</taglib>

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 --%>
