Hi, In Solr 8.6.1, a GET request or a HEAD request for a non-existing term in a managed resource (stopword or synonym) returns a HTTP status "404 Not Found".
$ curl -i " http://localhost:8983/solr/techproducts/schema/analysis/synonyms/english/foobar" | head -n 1 HTTP/1.1 404 Not Found $ curl -I " http://localhost:8983/solr/techproducts/schema/analysis/synonyms/english/foobar" | head -n 1 HTTP/1.1 404 Not Found In Solr 8.7.0, the same GET request still returns "404 Not Found", but the HEAD request now returns "200 OK" as if the term actually exists. $ curl -i " http://localhost:8983/solr/techproducts/schema/analysis/synonyms/english/foobar" | head -n 1 HTTP/1.1 404 Not Found $ curl -I " http://localhost:8983/solr/techproducts/schema/analysis/synonyms/english/foobar" | head -n 1 HTTP/1.1 200 OK I presume that's a bug?
