CouchDB-Why my rerduce is always coming as false ? I am not able to reduce anything properly - mapreduce

Question

I am new to CouchDB. I have a 9 gb dataset loaded into my couchdb. I am able to map everything correctly. But I cannot reduce any of the results using the code written in the reduce column. When i tried log, log shows that rereduce values as false. Do i need to do anything special while doing the Map() or how to set the rereduce value is TRUE??
A sample of my data is as follows:
{

}
}
My intention is to count the mapped values. My mapping function is as follows:
function(doc){
if(doc.release)
emit(doc.release.title,1)
}
Map results shows around 5800 results
I want to use the following functions in the reduce tab to count:
Reduce:
_count or _sum
It does not give single rounded value. Even i cannot get the simple _count operations right !!! :(
for screenshot,
Please help me !!!

Answer 1

What you got was the sum of values per title. What you wanted, was the sum of values in general.
Change the grouping drop-down list to none.
Check CouchdDB's wiki for more details on grouping.
