Subject Re: running views return nothing with couchdb1.5.1
Date Wed, 21 May 2014 14:32:18 GMT
Hi Radhika,

What does the server status say in futon?  (i.e. does it note that the
views are building or not?)

One side comment, the reduce functions that you posted will likely not do
what you expect when a rereduce is run.  I would suggest using _stats
(preferable solution,
http://couchdb.readthedocs.org/en/latest/couchapp/ddocs.html#builtin-reduce-functions
).

Cheers,
Mike
