hm. try to convert it to query q=-color:({* TO red} {red TO *}) and check
the explanation from debugQuery=true
I tried to play with my index
"q": "*:*",
"facet.field": "swatchColors_string_mv",
"fq": "-swatchColors_string_mv:({* TO RED} {RED TO *})",
I got the following facets:
"facet_fields": {
"swatchColors_string_mv": [
"RED",
122,
"BLACK",
0,
"BLUE",
0,
"BROWN",
0,
"GREEN",
0,
so, it works for me at least...
