Hello everyone, I will clearly tell you the problem.

In my program what i will do is, i will take google's top 10 results for a query and i will take the snippet's or title's from each result and compute the similarity between this returned snippet and the original query..

The computed similarity value is what i stored in the hash as key and the url's will be straightaway stored as hash value.. 

for e.g
$url={will contain the 10 url's grepped from xml result file}

$value=sim();#will contain the similarity computed for all the ten res
+ults;

%hash;
sim{
#here i compute similarity between query title and resulted snippet..
return $val;#i will return similarity value for each result
}


$hash{$value}=$url;#storing key & value in hash

#i will sort the keys in hash in descending order to get the highest v
+alue in top and print the url associated with that as a ouput..

Now i want to filter it by some threshold like keys higher then 0.4 or something..
