Actually, the number of query words has no impact on whether you should do 
scalar or associative clustering. Consider the query "Data". It may well be 
that by doing clustering on the set of top few docs that were returned for 
the query "data", we figure out that
"structure" and "Algorithm" are correlated with this query.
