Course: Building Knowledge Graphs with LLMs  
Page: [https://graphacademy.neo4j.com/courses/llm-knowledge-graph-construction/2-llm-graph-builder/3-explore-graph/](https://graphacademy.neo4j.com/courses/llm-knowledge-graph-construction/2-llm-graph-builder/3-explore-graph/)

Issue 1: The first 2 Cypher queries on this page return some duplicate results -- they should return `DISTINCT` results instead.

Issue 2: The 3rd Cypher query must specify the label for `e`, as in: `MATCH p = (d)-[*0..3]-(e: __Entity__ )`, or else the query does not do what is claimed. (Also, `0..3` should really be `..3`, since a `Document` node will never be an ` __Entity__ ` node.)

Hi,

Thanks for your comments.

re 1 - Ok. I think its important to show the raw output and let people observe what happens, individuals can add DISTINCT to the RETURN if they feel that is appropriate. I dont want to over sanitize hiding detail from people.

re 2 - Yes, when we created the course the ` __Entity__ ` label wasnt included by the LLM Graph Builder - we could improve that now.

Thanks again

Martin
