Earlier quoted context omitted.
Do you disagree there's a big implication here? Normally I'd agree with you.
I do; my suspicion is that it's people who didn't vote, trying to figure out what will happen in the near future.
Just FYI, participation was above 70%. ("The referendum turnout was 71.8%, with more than 30 million people voting. It was the highest turnout in a UK-wide vote since the 1992 general election" - BBC)
It's pretty safe to bet that a lot of those searches were from people who voted.
