From an unlikely source comes an excellent example of how one might formulate a plan to search for key words and phrases in documents. This informal Bloomberg.com article about the Lehman Brothers bankruptcy gives an excellent view of the process; and it may surprise you. I especially like this excerpt:
"The search terms came out of a session where 20 lawyers at
Valukas’s firm, Chicago-based Jenner & Block LLP, were “told to
sit down and be as imaginative as you can,” said Robert Byman,
a partner at the firm who helped with work on Lehman. The terms
were changed if searches produced too many hits, he said."
Good old-fashioned brainstorming at work…
