If I understand the docs right, it is only possible to sort facets by count or value in ascending order. Both variants are not very helpful for year facets if I want the most recent years at the top (or appear at all if I restrict the number of facet entries).
It looks like a requirement that was articulated repeatedly and the recommended solution seems to be to do some math like 10000 - year and index that. So far so good. Only problem is that I have many data sources and I would like to avoid to change every connector to include the new field. I think a better solution would be to have a custom TokenFilterFactory that does it. Since it seems a common request, did someone already build such a TokenFilterFactory? If not, do you think I could build one myself? I do some (script-)programming but have no experience with Java, so I think I could adapt an example. Are there any guides out there? Or even better, is there a built-in solution I haven't heard of? -Michael
