Hi, I have an application where I'd like to use a NoSQL database, but I still want to do range queries over two different properties, for example select all entries between times T1 and T2 where the noiselevel is smaller than X.

As a preface, I've been working with MongoDB for about a week now, so this may turn out to be a pretty simple answer. I have data already stored in my collection, we will call this collection content, as it contains articles, news, etc. Each of these articles contains another array called author which has all of the author's information...

I'm using Node.js for some project work and I would like to monitor my Mongo database (collection) for changes, basically fire an event if something gets added. Anyone know if this is possible? I'm using the node-mongodb-native drivers. If it's not I'd also like any available pointers on pushing data from the server (run with node) to ...

An example of this might be retrieving user preferences once a user has been authenticated. (BBC H...
