Only a fraction of Facebook’s more than 1 billion users will have access to the new search tool beginning Tuesday because the company plans to gradually roll it out during the next year to allow time for more fine tuning.

Not all the interests that people share on Facebook will be immediately indexed in the search engine either, although the plan is to eventually unlock all the information in the network while honoring each user’s privacy settings.

That means users can only search for content that have been granted permission to see by their online connections, Zuckerberg pledged.

“Every piece of content has its own audience,” Zuckerberg said.

Though the company has focused on refining its mobile product for much of last year, the search feature will only be available on Facebook’s website for now, and only in English.

Facebook’s decision to enter the search fray slowly reflects the formidable challenge that it’s trying to tackle. The “social graph,” as Facebook calls its trove of connections between people and things, is “big and changing,” Zuckerberg said. There are 240 billion photos on Facebook and 1 trillion connections.

Indexing all this, he added, is a difficult technical problem the company has been working on.

Although Facebook isn’t trying to fetch information across the Web like Google does, it’s clearly trying to divert traffic and ad spending from its rival. Facebook is hoping to do this by making it easier for its users to quickly find many of the things that are most important to them: movie, music and restaurant recommendations from friends and family; photo galleries of people they care about; and new connections to old friends and other people with common interests.

It’s the kind of personal data that has been difficult for Google to collect, partly because Facebook has walled off its social network from its rival’s search engine. Instead, Facebook has partnered with Microsoft Corp. to use its Bing search engine to power traditional Web searches done through its site. That partnership remains.

“’’For a certain set of searches, this is going to be far more powerful than Google,” predicted Ovum analyst Jan Dawson.
