Google Tuesday entered into its first partnership with a major professional services firm in hopes of attracting vertical industries to its search appliance with support and customization services.

Google, known for its consumer search and other online services, is aligning with BearingPoint, a systems integrator, which will launch a new practice centered on search using its own software platform and Google’s APIs for integrating the Google Search Appliance with diverse corporate data stores.

Google, which is trying to prove it has what it takes to be an enterprise software provider, currently has 20 smaller system integrator and professional services companies in the U.S. and another 14 in Europe that are part of its Google Enterprise Professional Program, which was established last September to help users deploy the Google Search Appliance.

Enterprise search is becoming a hot topic with research firm IDC noting in a recent report that both consumers and enterprise users alike have trouble locating information. Google, which dominates the consumer end of search, is pushing deeper into an enterprise market that has established enterprise platform players that offer a broad spectrum of search functionality along with gateways or connectors to third-party applications including Verity, Autonomy, Endeca, Fast Search & Transfer and Convera.

BearingPoint is stepping in to provide what Google doesn’t have to take on those players. It is the largest of the services firms to hook up with Google and will focus on companies in pharmaceuticals, banking, brokerage, high-tech and aerospace.

“The idea is we sell a very general purpose platform for search,” says Dave Girouard, general manager for Google enterprise. “The needs within different vertical industries and the different types of information sources they need to access vary dramatically. You need to be pretty deep into those industries to have hands-on knowledge of all those data sources. BearingPoint will scope how those companies can best use search and implement a customized version of Google search that works with their business.”

BearingPoint plans to focus on customizing and extending search to specific industry platforms such as enterprise content management systems; building in access control and authentication integration with corporate identity management systems, and developing interfaces for specific deployments such as call centers or research labs.
