com.orientechnologies.orient.core.metadata.schema.OClass.createIndex()
Creates database index that is based on passed in field names. Given index will be added into class instance and associated with database index. @param fields Field names from which index will be created. @param iName Database index name @param iType Index type. @return Class index registered inside of given class ans associated with database index.
