Neo4j

Neo4j + Lucene are a powerful combination. There is one feature I would love to see in this integration. Lucene was built on document stores, where a single document contains a collection of key value pairs. When we read a document we expect all related information to be contained in that document. So when you index documents in a MongoDB database, or records in a MySQL database (i.e. a row of a single table), in both cases you are limited to the key:value pairs contained inside the container. But a graph database differs from document stores; in a graph you generally benefit from a more exploded view of everything. So a Person node may not contain fields describing that person, instead Person may have relationships to other nodes like Hobbies, Employment, Address... When I index person, I would like to be able to use more context when I describe my Person to the Lucene index. I would like to be able to make a query to compose the set of fields for my Person node index to include Address.city, Employment.currentEmployer, Hobbies.favorite. I can't see that there is any way to do this other than to run a query that creates an actual field in my Person node derived from those related nodes, and then base my index on that materialised field. Lucene will accept only one label at a time, and there is no place to specify a query. Perhaps a great feature would be to be to allow the index creator to include fields from connected nodes. PS: I do see a challenge in implementing this. The index for the Person node above would have to be aware when the Address node changes so that Person node connected to it would be re-indexed. ...

Hi, I just updated to the latest Neo4j Desktop on MacOS. I was running a query then realized I wanted to terminate the query. I clicked on the X to stop the query, and the database stopped and disconnected rather than just stopping the query. Seems like a quirky bug. Thanks ... View more

I have recently completed the online course of "Data Science with Neo4j" however, after finishing the course i received a certification like this. It does not mentions the name of the course. However, I have another question regarding the Q/A. How can i check if the answer selected by me are correct or not, as i cannot see the question again once attempted. ... View more

Hi There, To drive the adoption of the graph dbs, it would be great if you guys can reach out to the datacamp.com and kaggle.com sites to collaborate on a fast track neo4j and Cypher material for speeding up the graph adoption into the data analysis and data science world. Thanks for reading this, have a good one! ... View more

Few good to have feedback on my initial exploration on the neo4j Etl tool Ui . In Explore and change your metadata section , Option to delete nodes & relationship Options to limit the properties we want to load for nodes and relationship. In Inspect your meta data section 1. It would be nice if we have option to edit the already created connection , Now if mistyped a field while creating the connection , I have to recreate the full connection again . In Import your data into Neo4J section 1. After import is complete it would be good to see the statistics of the import , Like no of nodes loaded , no of relationship loaded , time taken etc. ...
