Here is a workaround to configure a synonyms file on a WPSOLR index. You will need to reindex all your data after this procedure, and every time you update the synonyms file.

1. Install your synonym.txt file in your Elasticsearch server’s elasticsearch/config/analysis/ folder
2. Create a new index from Kibana with the command:

PUT /my_new_index

3. Create your index in WPSOLR with the same index name my_new_index
4. Configure your index in WPSOLR
5. Index your data in WPSOLR
