I am trying to use the full-text index provided by neo4j. I am using neo4j desktop community 4.4.5.
I was following the example here https://neo4j.com/docs/cypher-manual/current/indexes-for-full-text-search/#administration-indexes-fu...
I created the node using
CREATE (m:Movie {title: "The Matrix"}) RETURN m.title
and created the index using
CREATE FULLTEXT INDEX titlesAndDescriptions FOR (n:Movie|Book) ON EACH [n.title, n.description]
but when I call the procedure in neo4j browser using
CALL db.index.fulltext.queryNodes("titlesAndDescriptions", "matrix") YIELD node, score
RETURN node.title, node.description, score
I get this nasty error
Failed to invoke procedure db.index.fulltext.queryNodes: Caused by: java.lang.IllegalStateException: Index titlesAndDescriptions entered a FAILED state. Please see database logs.: Cause of failure:
