Assign "Others" label for nodes to handle unexpected inputs

Hi everybody,

We are using Neo4j to develop a software that can be use to store ETL data. Problem is that we don't know exactly the type of each input entity. Should we assign "Others" label for unexpected input type. There are some arguments that "Others" label makes data unclear and query performance can be quite low. Do you have any ideas or experience about this problem in Neo4j ?

Best regards,
