Other than digging into the internal low level 'httprequest' method, this is broken in 1.0.0.
There's a bug and an associated fix related for this, see:
This fix should make its way in 1.1.0 which will be released soon.
We make pretty heavy use of views and in particular the multi-get form of query:
It looks like this is very length limited, so that we can only supply from 50-100 keys, depending on the length of the keys supplied. The limitation must be on the query side, as a query with no keys parameter can pull down millions of documents with no problem. Is this a limitation that can be configured or altered in any way? Is there an alternative way to make this kind of query that get's around this limitation?
Great news! I'll look for the upcoming fix.
Version 1.1.0 has been released. This should fix this issue
