Hi John, I didn’t really want to use that plugin as it looked like it would lose control over a few things.
So, I did another search today and this was worked first time. http://adambalee.com/search-wordpress-by-custom-fields-without-a-plugin/
Really handy as I just add it to the functions.php. It’s adding an JOIN to the query but I haven’t noticed much in the way of speed loss so I’m going with this.
