1/2 of a circuit out with lost neutral

Residential home has 1/2 of a circuit malfunctioning( half of the outlets and lights work fine, the other half not).
There is power to all points and in fact, the voltage detector beeps on both the hot and neutral side equally. I dont understand how this can be. I know the neutral side is open because If i momentarily touch a wire from ground to the neutral side of a ceiling light it works.
So I need to find the open neutral. But I dont get the voltage detector reading. I didn't have a voltage meter with me when I went to check the problem.

The neutral will read voltage because the voltage is run through some device on the circuit that is turned on and has no place to go so you can read it on the neutral.

Ok, to see if i understand :
if i shut off all the light switches at, and, after the open neutral, leaving receptacles wired as usual then the neutral voltage should be gone ?

You need to shut off all switches and remove ALL loads on the circuit as any load will provide a path from hot back to the open neutral.

Normally the wire connected the neutral bus has no voltage with respect the neutral and ground busses. However, when the wire connected to neutral bus in a circuit gets disconnected or breaks and the circuit has a load that is turned on, the part of the circuit's neutral wire, not connected to the neutral bus, will indicate circuit voltage on a voltmeter with respect to ground or the portion of the neutral wire connected to the neutral bus because there is no current.
