Due to a reporting error, the story "Zuckerberg says IPO has been 'disappointing,' eyes search opportunity," which ran Tuesday, misstated how many searches Facebook users perform each day. The number is about a billion, according to CEO Mark Zuckerberg.
The tenth paragraph in the story has been corrected and now reads as follows:
Search is another big opportunity for the company, according to Zuckerberg. Facebook fields about a billion search queries a day, he said. They are mostly people searches, but also searches for company brand pages and applications.
