LFG Posting and Keywords not showing up

Howdy, I've posted a New World of Darkness game. I can pull it up on the LFG section when I search by game system. However, when I search by keywords it doesn't pull up. What am I doing wrong. What is "keywords" looking at. I have "World of Darkness" in the text of the game's description and that doesn't pull it up. However, if I do "nWoD" I see my game's posting. I'd appreciate any feedback I could get on how that system works so I can properly advertise my game. Thanks for the help!

Where do you set tags? I see on the campaign details screen where to add "Playing","Time", and "Description". Can you only set tags at creation and no other time or am I just missing it?

Go to your campaign click on the edit tags button

Thanks MK and Kristin. I've got it. I was in the campaign and you have to be a level higher. How do you put spaces in tags? I see many tags are multiple words but if I try and type one manually it creates a new tag. Thanks again.

I usually use the underscore _ to connect the words.
