Remove Live Search On ctl-shift-F

I love the app search feature (ctrl-shift-f).

However, if you type in one letter and pause for a split second, it hangs whilst it looks for every occurrence of the letter “a”. And with “anvil.xxx”, you can imagine how many that returns…

I think waiting for enter to be pressed is the best thing to do here. It reminds me of the well-intentioned-but-not-very-good live search on the old docs which was unusable towards the end of its life.
