Majority of Britons voted in favor of leaving the European Union, but were they totally sure about their decision — and about the E.U.? Apparently not, if a spike in Google searches is any indicator.

After the votes came in and Britain’s exit was officially announced, “What happens if we leave the E.U.?” and “What is the E.U.?” were the two most-searched questions in Britain on Friday, Google Trends reported.

The Brits seem to want to know all the facts about the E.U. after the vote, including which countries are in it and what’s going to happen next.

Other popular searches in the U.K. include “getting an Irish passport” and “move to Gibraltar,” the British territory on Spain’s south coast.

People were also more interested in the British pound as it plunged to a 31-year low in wake of the historic vote, which also sent global markets — including those in the U.S. —plunging.

The trending Google searches isn’t entirely a surprise. A 2015 Eurobarometer survey showed that Britons and Latvians knew the least about the E.U., the New York Times reported.

On Twitter, the number of Britons using the social media site doubled. There were 13,300 tweets per minute after Prime Minister David Cameron announced his resignation Friday morning. Even “The UK” was trending in its own country, an occurrence that Twitter says doesn’t happen very often.

By Friday morning, it seemed like some voters were already regretting their decision. A woman told British TV station Channel 5 News that if she could go back and vote again, she would choose to remain.

“I would go back to the polling station and vote to stay, simply because the reality is hitting us, and the regrets are filling in that we have actually left the E.U.,” the voter told a reporter.

Her whole family had voted to exit the E.U., she said.

There is still time before the split is complete. The process for Britain to exit the E.U. is estimated to take about two years, according to the Associated Press. The country will then operate on its own laws and immigration regulations.
