Will this provide more fuel for Yahoo-Microsoft-search negotiations? New numbers from comScore Networks show Google rising to a record 63.5 percent of U.S. search queries in November, continuing to steadily build on its market dominance.. Microsoft's Live Search, meanwhile, slipped to 8.3 percent of the market -- matching the previous low the Redmond company saw in August of this year.

In this case, Microsoft's results may have been hurt by the extended outage experienced by its Live Search Cashback service on Black Friday, the critical holiday shopping day. Before that point, the company had been citing Cashback as a source of growth for its search business.

Yahoo fell slightly for the month, to 20.4 percent of the market. Still, that's a huge chunk of market share that Microsoft would no doubt love to claim if it's somehow able to work out a deal with the struggling Internet company.

Starting next month, Live Search should be helped by the company's search distribution deal with Hewlett-Packard, which will distribute the Live Search toolbar and make Live Search the default on HP consumer PCs in the U.S. and Canada. However, a rumored Live Search deal with Dell hasn't yet been confirmed by either company, so it's not clear if that one will actually happen.
