We are trying to delete synonyms using the following curl command.

curl -v -X DELETE -u "username":"password" "https://gateway.watsonplatform.net/retrieve-and-rank/api/v1/solr_clusters/CLUSTER/solr/COLLECTION/schema/analysis/synonyms/english/mad"

We are getting as a result:

The message HTTP/1.1 405 Method Not Allowed means that we cannot perform this delete action. This is true or the curl command isn't correct?

By the way, do you know if it's possible to perform a 'delete all' operation/action?

Thanks!

The curl request is looking good to me actually.
Unfortunately Solr doesn't provide you means to delete all synonyms. For more details you could see the following Managed Resources wiki page.

From what I see the problem is related to the proxy part of the whole end-to-end path. Here is why:

< HTTP/1.1 405 Method Not Allowed
< X-Backside-Transport: FAIL FAIL
< Allow: HEAD,POST,GET,OPTIONS

Which means that allowed methods are: HEAD, POST, GET, OPTIONS only. You need to tweak Watson or DW (whatever underlying framework is) is order to allow DELETE methods for the Solr's base path.

As a proof for that you could test synonyms delete by calling Solr directly instead of using proxy / orchestration layer.

Try to modify _schema_analysis_synonyms_en.json file in a /cores/../managed/. Restart is needed.
