there have many methods to split signal power supply to dual power supply, but it depeneds th supply current you need.
if you needs only under 500mA, just put two capacitors in series between the positive and negtive side in the signal power rail.
and it creates the simplist dual +-45v power supply, but the center point is not really stable.
So add regulator like zener diode is the better way, also this way will
drop a bit voltage down.

Yes, the search feature sucks unless you know what words to search for...
You can do that but I would still recommend finding a transformer with dual secondaries or a center tapped secondary.
