Subject Re: implementing a random result request handler - solr 1.2
Date Mon, 07 Jul 2008 17:15:23 GMT
Well its simply a business requirement from my perspective. I am not sure I 
can say more than that. I could maybe implement a request handler that did 
an initial search to work out how many hits there are resulting from the 
query and then did as many more queries as were required fetching just 1 
document starting at a given random number .. would that work? Sounds a bit 
cludgy to me even as I say it.
