Hi Amith,
 
 
I tried with the options you gave and gave debug=true at the end of the URL.
I am getting output as 
 
 
<lst name="debug">
  <str name="rawquerystring">channel</str> 
  <str name="querystring">channel</str> 
  <str name="parsedquery">text:channel</str> 
  <str name="parsedquery_toString">text:channel</str> 
- <lst name="explain">
  <str name="http://hotmail">1.2682627 = (MATCH) fieldWeight(text:channel in 3), product
of: 2.828427 = tf(termFreq(text:channel)=8) 2.049822 = idf(docFreq=6, numDocs=20) 0.21875
= fieldNorm(field=text, doc=3)</str> 
  <str name="http://share">1.0026497 = (MATCH) fieldWeight(text:channel in 19), product
of: 2.236068 = tf(termFreq(text:channel)=5) 2.049822 = idf(docFreq=6, numDocs=20) 0.21875
= fieldNorm(field=text, doc=19)</str> 
  <str name="http://metacreek">0.6341314 = (MATCH) fieldWeight(text:channel in 10),
product of: 1.4142135 = tf(termFreq(text:channel)=2) 2.049822 = idf(docFreq=6, numDocs=20)
0.21875 = fieldNorm(field=text, doc=10)</str> 
  <str name="http://yahoo">0.5124555 = (MATCH) fieldWeight(text:channel in 0), product
of: 1.0 = tf(termFreq(text:channel)=1) 2.049822 = idf(docFreq=6, numDocs=20) 0.25 = fieldNorm(field=text,
doc=0)</str> 
  <str name="http://sharemarket">0.4483986 = (MATCH) fieldWeight(text:channel in 1),
product of: 1.0 = tf(termFreq(text:channel)=1) 2.049822 = idf(docFreq=6, numDocs=20) 0.21875
= fieldNorm(field=text, doc=1)</str> 
  <str name="http://Altavista">0.4483986 = (MATCH) fieldWeight(text:channel in 5),
product of: 1.0 = tf(termFreq(text:channel)=1) 2.049822 = idf(docFreq=6, numDocs=20) 0.21875
= fieldNorm(field=text, doc=5)</str> 
  </lst>

What does the numeric terms denotes?.With this numeric value will i be able to i set preference
for my search links?.If so how?.

Hi Amith,
 
Thanks for your reply.How do i set preference for the links , which should appear first,second
in the search results.
Which configuration file in Solr needs to be modified to achieve the same?.

It depends on several things:1) The query handler that you are using
2) The fields that you are searching on and default fields specified

For the default handler, it will issue a query for the default field and
return results accordingly. To see what is going on  pass the
&debugQuery=true to the end of the URL to see detailed output. If you are
using the DisMaxHandler (DisJoint Max) then you will have a qf, pf and bf
(query fields, phrase fields, boosting function). I would start looking at
http://wiki.apache.org/solr/DisMaxRequestHandler
