Neo4j-admin indexes

In 4.x versions of neo4j , we were wondering if there is a way to do index creation offline.
We were using CSV import using neo4j-admin, and as a post step we need indexes on some attributes and edges. Is that possible to do using Neo4j-admin or do we need to start the server up to do so ?


index creation is only possible when the database is online

thanks for the quick response @dana_canzano
