Description

Hi Guys,

We're using the SOLR Rest API in order to manage synonyms and stopwords with solr.Managed*FilterFactory.

{emphasis}The same applies to stopwords. I am going to explain the synonym case only from this point on.{emphasis}
Let us consider the following _schema_analysis_synonyms_en.json managedMap: {
"xxx#xxx":"xxx#xxx",
"xxx%xxx":["xxx%xxx"],
"xxx/xxx":["xxx/xxx"],
"xxx:xxx":["xxx:xxx"],
"xxx;xxx":["xxx;xxx"],
"xxxxxx ":["xxxxxx "]
}

I can add such synonym to keyword relations using REST API. The problem is that I cannot remove/list them as http://localhost:8983/solr/collection1/schema/analysis/synonyms/en/<entryname> where <entryname> is one of the map's key throws 404, or 500 (in case of xxx%25xxx):
