Cypher query to exclude specific TLD's from node values

Question

I have a single node containing domain names.

MATCH (n) RETURN n.name

"n.name"                  │
╞══════════════════════════╡
│""test01.bo-prod.htb""  │
├──────────────────────────┤
│""test01.bo-prod.local""│
├──────────────────────────┤
│""testa01.bo-prod.intra""│
├──────────────────────────┤
│""testa01.bo-prod.com""  │
├──────────────────────────┤
│""testa01.bo-prod.net""  │
└──────────────────────────┘

What is the most efficient way to RETURN only the domain names which are not local(exclude.intra, .local, .htb)? I am trying to avoid using regular expression search for performance reasons.

Answer 1

You can create a node label for that purpose then use the label when doing your query. For example:

1. Create the label, NonLocal

    WITH ['.intra', '.local', '.htb'] as excluded MATCH (n) WHERE not (any (x in excluded WHERE n.name contains x) ) SET n:NonLocal

2. You query becomes

   MATCH (n:NonLocal) RETURN n
