It is very common in German to convert verbs to nouns. There are several ways of doing so one of them is using the inifinitve form, capitalize the verb, and give it a neuter grammatical gender:
wühlen - das Wühlen
Thererefore whenever you find a noun not listed in a dictionary you may still find the verb it was derived from.
