             Summary: 
solr.ManagedSynonymFilterFactory/ManagedStopwordFilterFactory: URLEncoding - 
Not able to delete Synonyms/Stopwords with special characters
                 Key: SOLR-6853
                 URL: https://issues.apache.org/jira/browse/SOLR-6853
             Project: Solr
          Issue Type: Bug
          Components: Schema and Analysis
    Affects Versions: 4.10.2
         Environment: Solr 4.10.2 running @ Win7
            Reporter: Tomasz Sulkowski


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):
