Notice it looks almost the same as for us, but just lacks some formatting. They interpret the code but don't index it as code, so I don't think you can search by source code. The search operators don't give information otherwise unseen by us, they just allow different ways of searching and listing information. Hopefully you understand what I mean as it was a bit difficult to explain.
I'm curious why you're looking for web pages that use
in their source code. Maybe we can work out another solution to what you're overall trying to do.
