What does "Order" do for technology?

[portalreaper]

I've added 2 new technologies. 1 worked fine, the other isn't.
The 2nd one seems to be working, but it doesn't show up on the tech tree, and I believe it's because of the order thing.
Can anybody explain what to do with it and what it means ?? The first one, I think I just put pretty much random numbers, and the right prequisite, and it works. But no matter what I try for #2, nothin.

Do you know how item ordering works? It's the same thing, but limited to the unlocks of a research. So you could have a belt unlocked with an inserter, and by default the order is alphabetical. Using order will let you change that order.

Otherwise, there's little documentation on how ordering works and I can't help you with this other than give you some info. Sorry.

Assuming that ordering is the same as recipes; the game orders them by the order string, then if they share an order string, by name.
