Google, Lycos, and Yahoo in separate efforts are putting their search technology to use to help survivors of hurricane Katrina find people and information through the Web.Google last night announced via its blog two new search tools for Katrina relief. The company created a Katrina People Search people finder tool and a special search index that returns results only from Katrina-related Web sites, according to Google.Google officials said the company indexed numerous public Katrina-related databases including the Katrinasafe.com site, which lets people involved in the disaster report their status or search for missing friends or relatives. Lycos, meanwhile, is offering a similar search page that lets users scour multiple Hurricane Katrina sites for information about survivors and missing persons.Yahoo, in addition to offering a people finder tool for Katrina sites, also launched a slew of message boards for coordinating people search. These public message listings include “Missing,” “I’m Okay,” and “Pets Lost and Found.” Yahoo also lists other services grouped by city, parish, university, and relief center. Technology Industry
