Filing notice of liens.
Upon presentation of such lien notice to the auditor of any county, he or she shall file the same, and endorse thereon the time of the reception, the number thereof, and shall enter the same in a suitable book or file (but need not record the same). Such book or file shall have herewith an alphabetic index, in which the county auditor shall index such notice by noting the name of the owner, name of lien claimant, description of property, date of lien (which shall be the date upon which such expenditure of labor, skill or material was completed), date of filing and when released, the date of release.
