Google QDR Parameter

Other than Google Realtime, Google also allows

us to search reuslts crawled in the past 24 hours.

The question is, what if we wanna see more recent results? say.. from the past 10 minutes?

That’s where the QDR parameter comes in handy!

The QDR parameter tells the engine how fresh the displayed results should be, and lucky for us – Google has neglected securing it.

Here’s what the original URL looks like:
http://www.google.com/search?q=Test&hl=en&prmdo=1&prmd=b&source=lnms&tbs=qdr:d,dsc:1

This will bring back results from discussions including the word “test” crawled in the last 24 hours. If we’ll take a closer look at the qdr parameter, we’ll notice that it has a value – d (which stands for “day”).

For 10 minutes, we’ll change this value to S (for seconds) followed by the number 600 (for 600 seconds), like so – qdr:s600.

Here’s the full URL:
http://www.google.com/search?q=Test&hl=en&prmdo=1&prmd=b&source=lnms&tbs=qdr:s600,dsc:1

The results will now show discussions crawled in the past 10 minutes.

Could be useful for tracking the most recent discussions on a subject and replying before everyone else does as well as other cool things.

Quite simple and could obviously be used with more sophisticated quarries :]
