python solr2es-mapping.py /path/to/solr/schema.xml
it will produce ES mapping in /path/to/solr/schema.xml.json
Then it can be used to create ES indices:
curl -H 'Content-Type: application/json' -X PUT localhost:9200/new_index -d @/path/to/solr/schema.xml.json
Custom language analyzers are created from Solr definitions instead of reusing ES built-in ones.
