I was looking at the Github repos for Sonic, and a PHP library for working with it: https://github.com/ppshobi/psonic/blob/master/api-docs.md and I'm scratching my head over: what's the difference between the popping and flushing operations?

Specifically, there's a "pop" method which: "pops an item out of index" and a "flusho" method which "Flushes the indexed text from an objects". They kind of sound awfully similar and take similar args.

Otherwise it all looks pretty straightforward - just that one small conceptual thing might be explained a bit more in the docs.
