Elasticsearch supports synonyms through their synonym token filter, which expects a file of all the synonyms to be present at a particular location on the server file system.  
Our cluster is configured to be shared by multiple tenants.

1. Does ES offer an admin API for user to upload the file?
2. Other than specifying the file location in the synonym path, does it support other protocols? For example, a http url as the value of synonym\_path?  
Thanks!
