'Aufspüren' is a separable verb. The prefix 'auf' is separated from the verb in a main clause and placed at the end of the sentence.

The detective tracked the thief down in a small apartment.
The verb 'aufspüren' is closely related to the noun 'die Spur' (the track/trace). Literally, it means to find a track and follow it in order to discover something or someone.

The police are trying to track down the perpetrators' trail.
In the concrete meaning, 'aufspüren' is often used with people, animals, or hidden places. Typical objects are 'einen Vermissten' (a missing person), 'ein Tier' (an animal), 'ein Versteck' (a hiding place), or 'einen Schatz' (a treasure).

In a figurative sense, 'aufspüren' is used for abstract things that you find through analysis. Common combinations are 'Fehler aufspüren' (to detect errors), 'Probleme aufspüren' (to detect problems), 'Talente aufspüren' (to discover talent), or 'Trends aufspüren' (to detect trends).

to find
'finden' and 'aufspüren' can both mean that you discover something. 'finden' is the normal, broad word. It fits when you are looking for something, but also when you discover something by chance. 'aufspüren' sounds more targeted and stronger: you search intensively, follow clues, or examine something carefully. The word is especially suitable for people, tracks, errors, or hidden things. Learners may confuse the words because the result is similar. The difference lies in the path to get there: 'finden' only says that you discover something; 'aufspüren' emphasizes the active, thorough search.
