NEW YORK ( TheStreet) -- Facebook ( FB) CEO Mark Zuckerberg touched on a number of topics Tuesday night in his chat at a TechCrunch conference, but the topic that's getting the most attention is the company moving into search. Why wasn't search made a bigger deal in the company's S-1 filing when talking about the business? Doing a keyword search for "search" in the company's S-1 filing before its IPO, and the hits are limited, at best. Nowhere in the filing does it mention search as a business, yet Zuckerberg made that a focus during his discussion with moderator Mike Arrington. Arrington asked about Google ( GOOG) and its social network, Google+, and whether that "pissed him off." Zuckerberg shied away from that, but did talk about search, which he thinks is an "interesting opportunity" for the company. "Search is interesting. We do on order of a a billion inquiries a day, and we're not trying," Zuckerberg said. "I think that there's a big opportunity for us in search , we just have to find it." If there was such a big opportunity in search, why was this not at the forefront of discussion? Why not talk about this opportunity and get investors excited about it before the IPO, which went anything but swimmingly? This seems like a bit of a marketing ploy to me, but it's gotten the attention of Wall Street analysts. "The biggest takeaway from today's event was Zuckerberg's confirmation that Facebook would eventually enter the search business," wrote Jefferies analyst Brian Pitz in a research note. He rated shares buy with a $30 price target. Zuckerberg said that search was a "big opportunity," and said could help people "locate good sushi restaurants, or locate people who have worked for a specific company." Pitz was careful not to get too excited over the prospect of search, but noted there is upside for Facebook's revenue, as it's not included in estimates. "Facebook already has a team in place working on search, which is not surprising given the company sees so many daily queries. But monetization will take time and we think the relatively narrow scope of Facebook's search limits overlap with GOOG, for now," Pitz said.
