I think will be a helpful option to exclude digits from the facet and display only characters.

The change alters the user interface, so before and after screenshots should be added to document the UI change. Make sure to capture the relevant region only. Use a tool such as Aviary on Windows or Skitch on Mac OS X.

It's likely this issue predates Contrib.social: some issue and comment data are missing.
I believe this can also be solved by an existing facet processor "Exclude specified items".
How to:
- On your glossary facet, enable "Exclude specified items".
- In your index processor settings, if you enabled "Group Numeric (0-9)", then you should enter 0-9 in Exclude items, otherwise, you should enter all numbers from 0 to 9 separated by comma.
