The more specific the task the better- you cannot just use Savoir-Faire to find out what is going on in the galaxy (you can monitor transmisisons to do something that general); I would need to know what it is you are specifically trying to find out.
Same with Jedi Lore based things; one person cannot be trying to find out about all Lore related issues in the storyline at once. To relate that to what Melkor just said- you could pick out something from the crystal to look into, or you could look into the invasion of Damaria (or even a broader look at the Malphan Wars), but not both things.
I'll allow a certain amount of flexibility and leeway and some minor things don't take up your entire yearly choice, but each character can only manage one big reveal/accomplishment about one specific subject.
