In the neo4j browser, when I click on * under 'Node Lables' returns nodes of all label types, and when I click on any node, I could see the label name appearing at the top. However, the following cypher query is not working.

    MATCH (n:`Home`) RETURN n LIMIT 25
    MATCH (n:Home) RETURN n LIMIT 25

I have turned on the CYPHER 2.0 property in the neo4j.properties. Do I need to change any other settings? I see these lablels when I export as JSON

回答1:

I noticed this problem when upgrading. Did not manage to find out the problem, but what I did was delete the database and recreate it entirely -> matching on labels worked again. Of course, deleting the entire database and recreating it is not possible in all situations

回答2:

Specify START Clause and it works, START n=node(*) where n:Home RETURN n LIMIT 25 . The START clause way worked irrespective of the cypher_parser_version=2.0 property in neo4j.properties commented/uncommented. But I still wonder why your query does not work..
