What’s up with Microsoft’s purchase this week of search startup Powerset amid rumors that Redmond also is readying another takeover bid for Yahoo? In today’s Tech’s Bottom Line, Bill Snyder calls the acquisition “a smart move that will help the stumbling software giant get back in the game.” Powerset’s semantic search technology “will give Microsoft incremental advantages, and that’s a good thing,” Snyder writes. “But to really challenge Google in search, Microsoft will have to do something extraordinary. One possibility: an engine that does a good job searching multimedia content, and not just tags or captions. … A search engine that allows consumers to find an image or a song would be the game changer Microsoft desperately needs.’ Snyder also has a heads up for engineers: “Microsoft has hung out a ‘help wanted’ sign for engineers skilled in search technologies.” Satya Nadella, who heads Microsoft’s search business, said, “We’re looking to add even more talented engineers to the San Francisco team to accelerate our shared progress. If you’re interested in joining the team, drop us a line.”And drop us a line telling us what you think about Microsoft’s latest search move. Technology Industry
