with Fess 12.3.1 I cannot put labels in alphabetical order while in Fess 11.4 it was possible putting a progressive number on “value” field on label definition.
Tried also with Display Order but no differences.
Try to change sort in app.xml.
<component name="facetInfo" class="org.codelibs.fess.entity.FacetInfo">
Yes, this works.
Thank you very much
