Schema Index

[Daniel Silva]

Hi,

I could not figure out how I can use Neo4jClient to create and use indexes defined in schema. This docs did not helps: https://github.com/Readify/Neo4jClient/wiki/indexes

Can someone help me?

Best regards,

Daniel.

Ok, I found that a can use it like this:

graphClient.Cypher.Create(" INDEX ON :Person(Name)").ExecuteWithoutResults();

After this I would query normally:

graphClient.Cypher

                .Match("(p:Person)")

                .Where((Person p) => p.Name == "Any name")

                .Return(c => c.As<Person>())

                .Results;

The only problem that I'm facing now is that Neo4j only finds a Person with a exact Name: "Any name", but I wanted to query using full text search.

Hi Daniel,

 

Schema based indexing, which is what you are using via Cypher there, only supports exact indexing.

 

Full text indexes are not supported in Cypher, or via schemas yet. You’ll need to use the legacy indexing APIs to manually index individual nodes.

Ok, Tatham. Thank you for helping.

By the way, what do you think about adding some Lucene abstraction classes in Neo4jClient instead of only string queries? I would like to contribute on this, because I´m really loving Neo4jClient and I have never contributed to an open source project before.

Daniel, any contribution to Lucene integration would most likely deprecate soon.

If they’re related to querying via Cypher, I can imagine they might be useful after Lucene support moves from START to MATCH.

 

What syntax were you thinking of?
