search result score
How can i get the search hit scores? I found a boost field but it is
1.0 for all the hits. Is there anyway to have something like google
page rank on these results?
Thanks. Mike

I believe PageRank could be obtained by calling
DistributedAnalysisTool. Actually, it should be called
couple of time to get boost score value closed to a
true PageRank, coz each call is just one iteration.

Are you sure you want the PageRank?
If you just want the rank of a particular result hit against the given
search criteria, use the following code in your search result JSP:
<%
float resultrank = 0;
FloatWritable indexnumber = (FloatWritable)hit.getSortValue();
resultrank = indexnumber.get();
%>
if you also want to display it in a cool bar next to the result,
insert this code:
<%
float relevance = Math.round(indexnum * 5);
out.print("<table width=\"50\" border=\"1\" cellpadding=\"0\"
cellspacing=\"0\"><tr>");
out.print("<td width=\"" + relevance + "\" bgcolor=\"blue\"
height=\"4\"></td><td width=\"*\" height=\"4\"></td>");
out.print("</tr></table>");
%>
;)
Have fun...
Cheers,
Daniel

you should run linkAnalysisTool for your webdb and run
updateSegmentFromDB to update score to your segments,
