Improve 008 field facet for Pulbication Year
Currently, Alma only acknowledges the first 4 digits after the 6th position as "Publication Year".
The MARC21 standard has a much more in depth system, and Alma facets should account for the following features.
1.- Alma currently only recognizes numbers, but in the MARC21 standard the letter 'u' is established as an unknown/wild card.
For instance, 19uu should be recognized as 1900 or 19??. 182u = 182?, 1uuu = 1??? and so on.
2.- The 6th position letter defines how many specific years and what those years mean, up to 2 different years.
Alma now only recognizes what is after the letter and only 4 numbers, but while s denotes single year, m denotes multiple years and k denotes ranges. Again, up to 2 different years, which means Alma should be able to deal with the Years from position 6 to 14. 6th position being the letter (s, m, k), and the next 8 positions the years.
Example:
s1900#### = 1900 (current behavior, works correctly except it apparently ignores the s).
m19002010 = 1900 and 2010
k19002010 = From 1900 to 2010
Since now everything works as if it was set to 's', with Alma ignoring the second year, here is how m and k should work:
m = multiple years. Hence, Alma should use both years as separate facets.
If "m18992000" exists, Alma should make both a 1899 and a 2000 facets.
k = range. Hence, Alma should have a range facet.
k18992000 = "1899 - 2000" or similar.
If u exists, the same should apply.
m19uu2010 = 19?? and 2010 become separate facets
k19uu2010 = 19?? - 2010 facet appears.

Thank you for raising this. I'd like to extend this idea to:
a) also take account for 008 pos6 "r" for reprint. An edition from 2015 but reprinted in 2028 should, according to M21 standard have pos6 "r", "2018" in pos7-10, and "2015" in pos11-14. Now only 2018 is displayed, which is incorrect for publication year in these cases.
b) not restrict this correction to facets, but also to the Primo VE addata section, which is being used in Citation services in Primo. In this case, too, the addata/date field is :
"date" : [ "2018 - 2015"], as if it was a serial, perhaps, but Citation services only takes the four first digits, i.e. 2018, instead of the publication year,
