Inspection of Google Advanced Search Parameters

Deciphering the code

Let us start with: “&as_qdr=y10”, and then we will march ahead to dig out some more virgin treasures from this treasure blog land.

I searched and searched a lot on this particular term and finally reached to the unofficial conclusions as shown in this pictorial content:


I used the word ‘unofficial ‘since these full forms have not yet been confirmed by Google publically. But that hardly affects our topic so it is better not to waste time. Lets move ahead!

Dissecting the code

Example1: Suppose if at the end of my query URL (check out my previous post), I am appending the search parameter ‘&as_qdr=y5’, then it will Filter out my query result to fetch the results crawled by the search engine within the past 5 years


Example2: Similarly, if I am adding the parameter ‘&as_qdr=d12’ then as per my understanding and perhaps which is the right revelation, I will get all the results fetched by Google within the past 12 days.
The operators thus used in this form of query are described here:


d[number]: Gives the search result within the required number of days (e.g. d5 means within 5 days)

w[number]: Gives the search result within the required number of weeks (e.g. w5 means within 5 weeks)

y[number]: Gives the search result within the required years of weeks (e.g. y5 means within 5 years)

Improved search query

Scoring higher over the as_qdr queries is the ‘tbs’ that stands for ‘Time Based Search’ parameters. Though, both of them are equally efficient in getting you closer to the desired results, it is just that ‘tbs’ helps you penetrate way deeper into your search and allows you to obtain results updated by google in the past few hours, minutes and even seconds. Pretty magical!

Example3: Just to cite an example, the query, http://www.google.com/search?q=googlepenguin&tbs=qdr:m1


Will fetch the all the links created or updated about Google Penguin in the past 1 month.
