[ hap]
While this verb is attested in Continental French, it is in the sense of ‘to use up completely’. Anglo-Norman and English attest to a semantic shift to the sense of ‘to go through, examine’ which is attested in English from the end of the 15th century. The OED suggests that this shift in meaning might be due to its visual similarity to the verb pervise v., meaning ‘to look over, examine’, derived from the past participial stem of pervidere (DMLBS 2249b)
