In 22.05, the pubdate index that searches pos. 7-10 in field 008 works well if searched for one year only (e.g. 1999). However, searching for a date range, as suggested in the pulldown menu where it says "Publication date (yyyy-yyyy), doesn't yield anything at all. Thus, "1999-2002" or "1999 - 2002" return 0 results, even though there are records with pubdates 1999, 2002 and the years in between, and they can be retrieved by searching for one single year as mentioned above.
