Thomas Corthals commented on SOLR-6853:
---------------------------------------
There is a workaround, _almost_: percent-encode the synonym/stopword twice
(e.g. {{#}} → {{%23}} → {{%2523}}). This is at odds with [RFC
3986|https://tools.ietf.org/html/rfc3986#section-2.2] _and_ it still doesn't
work for slashes. An actual RFC compliant fix would be preferable.
You'll notice that both {{C++}} and {{C%2B%2B}} get interpreted as {{C␠␠}} (C
SPACE SPACE). {{C%23anything}} acts like you'd expect from a fragment
identifier, which it clearly isn't.

> Project: Solr
> Issue Type: Bug
> Components: Schema and Analysis
> Affects Versions: 4.10.2
> Environment: Solr 4.10.2 running @ Win7
> Reporter: Tomasz Sulkowski
> Priority: Major
> Labels: ManagedStopwordFilterFactory,

> 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):
