I was playing with the ManagedSynonymFilterFactory to create a synonym list with the API. But I have difficulties when my keys contains special characters (or spaces) to delete them...
I added a key ééé that matches with some other words. It's saved in the synonym file as ééé.
When I try to delete it, I do:
curl -X DELETE "http://localhost/solr/mycore/schema/analysis/synonyms/english/ééé"
error message: %C3%A9%C3%A9%C3%A9%C2%B5 not found in /schema/analysis/synonyms/english
A wild guess from me is that %C3%A9 isn't decoded back to ééé. And that's why he can't find the keyword?
