How do I make Konqueror adjustable? Such as, how do I make Konqueror change the search engines?

For a start, I don’t want to use google.co.uk, that is not where I am.

Nor do I want to use google at all…

I would like to configure a new search engine, such as ask.com .

How do I go about this?

In the left corner of the search bar (top RHS of konq window), you should see a tiny icon with a drop-box arrow on it.

Click that and you can then select your search engine.
