Search for multiple pages

This is a really simple one. I think it would be very useful to be able to search in your currency log, messages, notifications, and forum activity. There's been a few times I've wanted to find something in the currency log and had to go through multiple pages skimreading to find it. It'd be great if the functionality was the same as searching in the regular log. For messages, notifications, and forum activity, it'd be nice if it was a search similar to forums, by being able to search by title only or within the message/forum contents as well.
