I decided that I needed to change the default search provider in Safari from Google-US to Google-UK. I thought that this would be a five second trip to Safari preferences, how wrong was I.
For some strange unknown reason Apple has decided to hard code the search provider (Google US) into the Safari application itself. I found various guides on the internet on how to change the default search provider, but they all required use of the Terminal and the not very easy to use editor Vi. Not forgetting that if you make any mistake when editing, it will render Safari completely useless.
After almost giving up I did one last search on Google and came across an excellent Safari plug-in AcidSearch. This plug-in not only lets you change the default search provider in Safari, it also lets setup multiple search providers which you can search on via a handy drop-down menu.
It seems development on AcidSearch has ceased and no longer works with latest version of Safari. All is not lost though as I have found a worthy replacement. Introducing Inquisitor! Inquisitor does a lot more than just allow you to change the default search engine, it completely enhances the entire search experience.
