I expected to be able to do things like this:

Example text to find
1, Passed,0,Q_Mitel2_with_hub_Env1,1,
1, Passed,0,Q_Mitel2_with_hub_Env2,1,
1, Passed,0,Q_Mitel2_with_hub_Env3,1,

But if my regex search string is
^1, Passed,0,[_A-Za-z0-9]

Then it only finds text up to 1, Passed,0,Q

How do I get it to find all of text like A_BC_D and A_CCCCCC_S

	Putting a set of characters between square brackets will only match
one character from the set. You can then use the usual repetition
operators (?, *, or +) to match more than one character (so in your
case, ^1, Passed,0,[_A-Za-z0-9]+ should do what you want).

That is correct behaviour! It finds exactly one character of the given set. If you want to find more, you need to add a + for example.
