For the meaning: Think of being "on" (auf) the "track" (Spur) of something. You are actively trying to track it down (aufspüren). The action itself is "das Aufspüren".

📜 Poem about Aufspüren

Im Netz der Daten, tief und weit,
Verloren ging die Kleinigkeit.
Doch unermüdlich, Tag und Nacht,
Wird nach dem Fehler Wacht gemacht.
Das Aufspüren, es braucht Geduld,
Bis man erlöst von aller Schuld,
Den Bug entdeckt, die Spur verfolgt,
Und das System nun wieder rollt.

--- Translation ---

In the web of data, deep and wide,
A little detail went to hide.
But tirelessly, by day and night,
A watch for errors is kept tight.
The tracking down, it patience needs,
Till one is free from guilty deeds,
The bug detected, the trace pursued,
And the system runs renewed.

❓ Little Riddle

Ich bin kein Fund, doch führe hin.
Ich bin der Weg, der zum Gewinn.
Ein Detektiv braucht mich gar sehr,
Auch ein Spürhund kann nicht ohne mehr.
Bin ich erfolgreich, ist’s entdeckt,
Was gut versteckt, ans Licht gestreckt.

Was bin ich?
... Das Aufspüren

--- Translation ---

I'm not a find, but lead the way.
I am the path to win the day.
A detective needs me urgently,
A sniffer dog can't work without me.
If I succeed, it is revealed,
What was well hidden, now unsealed.

What am I?
... The act of tracking down / detecting (Das Aufspüren)
