Question

I am trying to design my first NoSQL database, and as an example I am trying to grab content from Twitter. I have though some difficulties deciding how to structure the document.

If I am grabbing from several tags (e.g. #Programming #stackoverflow #nosql etc.) each day, how should I structure the documents so they doesn’t grow too large and I still can do analytics based on all the tags?

I thought of creating documents like this:

/{day}/{hashtag}

This would get me the following:

/28052012/Programming

/28052012/StackOverflow 

/28052012/NoSql

But how would I then get the latest 5 Tweets from the combined hashtags?

Answer 1

You should use $or operator. It can use indexes and will allow you to perform efficient queries.
