perception, for those articles, I used:
www.news.goggle.com
and put in
Iraq gases Kurds
I usually start out with my search words in " ". This way the words become related to each other in a more direct way. This time I got nothing until I took the " " off.
Also, the search words do not matter what order they are placed in and as mentioned before; use as few words as possible that is the best indicators of what you want. Then play around with those words.
That's my methodology. Also, I try not to take out of context, if you notice - those articles give good agruments for both sides. That is the reason in true Politics, there is no right and wrong - just the way you play the game. (I will admit, if the game is being played unfairly, I will be unfair - now blatham, he has too much conscious me thinks - ha!)
