Hi Dmytro,

Can you please present an easily reproducible scenario, preferably using the default "bin/janusgraph.sh start", like I showed, with gremlin console output and starting with an empty db/cassandra and db/es directories. From your description it is not clear what exactly happened.
And to be sure, when you first added nodes and then defined the mixed index, you also made sure that the graph was reindexed.
