I have a string field containing values such as "1khz" "1ghz" "1mhz" etc.
I use this field to show a facet, currently I'm showing results in facet.sort=count order. Now I'm asked to reorder the facet according to the unit of measure (khz/mhz/ghz). I also have 3/4 other custom sorting to implement Is it possible to plug in a custom java class to provide custom facet.sort modes? Thank you Giovanni
