Hello
Using the documentation and this answer as guide
http://stackoverflow.com/questions/22105716/how-do-i-create-a-case-insensitive-automatic-orientdb-index
I tried to create an index
CREATE INDEX Class.name ON Class (name COLLATE CI) notunique_hash_index
The server console said
com.orientechnologies.orient.core.exception.OCommandExecutionException:
Error on execution of command: sql.CREATE INDEX Class.name on Class (name
COLLATE CI) NOTUNIQUE_HASH_INDEX
