"It is less than thinking of something, but more like applying conditions, which must be met. For example if I would track 'every lifeform', everything, that is considered alive would be tracked. However, the spell does not disciminate between targets, so I don't know anything about the tracked objects, apart from their location and that they meet all conditions. However, the spell also has its limits, track too many things at once, regardless if intentional or not, and you just wasted a ton of mana and got a headache. Basically, to track something you want, you need to know what makes it different from most other objects in the spell's range. And as Nawar demonstrated the spell can also be countered, as he prevented it from tracking himself during his escape." Iṃgor elaborated while looking closely at the marks on the sword, memorizing them while looking for a common pattern they all follow.
