We are harvesting 200K+ records from our Photographic Collection which have a huge variety of date formats. They are slowly working through the metadata to try and get funnelback to index accordingly, however they are struggling with the options for Month/Year. Changing everything to ISO 8061 is probably not an option unfortunately.
According to the help page, the only parse-able date format for Month/Year is YYYY-MM (Short ISO 8061). All other formats mention DD or are just YYYY.
Are there any "longform" accepted formats for Month/Year that will work. For example:
"21 September 1963" is indexed correctly for the year 1963.
"September 1963" however is indexed as the year 2000!
Or would it work if a range was added to the start, i.e:
"1st-30th September 1963" ?
