Problems setting a default Bucket search view in Sitecore

I’ve been doing a bit of customisation to a Sitecore 7.5 instance that is going to have to store a lot of nodes in one particular area. Naturally, thought of using buckets, which would be ideal. I’ve a few things to cover in this, but I’m going to start at the end – and the hardest problem.

I wanted to set a default search to run when someone comes to the bucket in the content editor.
