Google Number Change

Has lessened for small retrievals
Unfiltering may increase
Add &filter=0 to turn off clustering

Google Supplemental 2003-07
Formerly separate database w/ labels
Not refreshed frequently
Retrieved only when <200-800 results
Label is now gone, Refreshed more often
But still there?

In Google Results URL
Change &as_qdr=
d[number] - past number of days
w[number] - past number of weeks
y[number] - past number of years
&as_qdr=y3
For past 3 years

Image Searching Issues

Link Searching
Google: Partial results, no combine
Live: Commands pulled in March
link:, linkdomain:, & inurl: (use + to make work)
Yahoo: Best bet
link:http://www.ibm.com/employment -site:ibm.com
Be sure to include full URL and http://
Also can use linkdomain: with no http://
linkdomain:ibm.com site:yale.edu

Personalization
Google ranking now defaults to it
If you are signed in
. . . And do not turn it off
Same results, just slightly different order
Remember: Add &pws=0 to turn off
Trend for future or dead end?
