I have a Node with a two letter Name "HR" which is short for Human Resources. When I search for it in Bloom, Bloom refuses to expand and complete it, even though it's an exact match. I'm guessing that you have to type at least 3 characters before Bloom gives you a hint. This makes some sense, as the user would get an unhelpful huge list of possible matches after typing one or two letters. I think you should allow 1 or 2 character searches to complete IF it's an exact match. ... View more

Desktop 1.3.11 (Im not sure if the Browser has its own version number) MacBook Pro OS X 10.15.7 (Catalina) Using the Movie DB: MATCH(p:Person) RETURN p.name ORDER BY p.name The last person is: "Zach Grenier" If you scroll to the bottom of the cell you see: ├────────────────────────┤ │"Vincent Ward" │ ├────────────────────────┤ │"Werner Herzog" │ ├────────────────────────┤ │"Wil Wheaton" │ ├────────────────────────┤ │"Zach Grenier" │ └────────────────────────┘ BUT if you zoom the cell so it takes up the full screen, the last name is not visible. If you copy the text in the cell, you do pick up the last name that off the visible area. This occurs with both the Table and Text. See: ... View more

Hi, I am following these docs: https://neo4j.com/docs/operations-manual/current/cloud-deployments/neo4j-aws/automation-aws/#_deploying_neo4j_community_standalone, and the script provided is not working. The error message thrown is "S3 Error: Access Denied". The S3 URL it is trying to access is this one http://neo4j-cloudformation.s3.amazonaws.com/neo4j-community-standalone-stack-4.2.0.json. When trying to access it directly through my browser, it throws an Access Denied error. It looks like the community template isn't available in the public Neo4J S3 bucket. The other templates (enterprise and cluster) are working fine though. Maybe the S3 settings aren't correct on this specific file, or is this template not available at all? Thank you, ... View more

Somebody else had this problem. When I tried to downgrade to 4.1.4, the Downgrade button is dimmed. (I'm currently on 4.2.1.). The reason why I want to do this, is because Neosemantics only supports 4.0 and 4.1. (P.S. It would be nice if all Neo4J supported code could move forward when a new release is made.) At first, I thought maybe it's because I've been deleting old versions of the DB. So, I spun up a new DB with 4.1.4 but still the Downgrade button is dimmed for my old DB. I also tried upgrading my new DB to 4.2.1 and then trying to downgrade to 4.1.4 but for this new DB that I would have thought would "know" about 4.1.4 doesn't seem to. Again, I can't Downgrade to a previous version. See also: How to downgrade neo4j Newbie Questions Downgrading you can do in the Neo4J desktop program, stop the database. Click on the 3dots and select manage; select the upgrade tab and select the correct version. Alternatively you might want to create a new database with a recent 3.x version and use that for your application. [image] ... View more

In this tutorial: Neo4j Graph Database Platform Creating Relationships - Introduction to Neo4j 4.x Series There is the query: MATCH (a:Person), (m:Movie) WHERE a.name = 'Michael Caine' AND m.title = 'Batman Begins' CREATE (a)-[:ACTED_IN]->(m) RETURN a, m with an explanation that this query will create a cartesian product but it does NOT explain how to avoid that! Avoiding a cartesian product is explained here: Avoid cartesian product when create relationships Cypher Hi! I'm new to neo4j and I try to find some help here. I have two sets of nodes say one is people and another is car.I want to create relationship between these two sets of nodes but I don't want to create relationships base on cartesian product of result return by match since it will take much time. The cypher statement I use like below: MATCH (a:test_11),(b:test_12) WHERE a.car ="0" AND b."price" = "1" MERGE (a)-[r:own{time:2020,location:"LA"}]->(b) Is there a way to write cyher which ca… (I would have made a Pull Request on it, but I don't know where it lives in github.) ...

Hi, we sometimes get this error if we use the bloom shortest path function to find nodes between 2 nodes. We would really like to know how to fix this issue? We don't understand what is causing this error message. Resetting the perspective seems to fix it temporarilly, however after using the shortest path function a few times, the error message appears again. After it appears it will always appear when using the shortest path function until resetting the perspective. Sometimes we also get at first "Expected NO_VALUE to be a path" error in bloom when using the shortest path function between 2 nodes. After that happens we get unkown variable n@412 error on all other nodes with the shortest path function, which had worked before the "Expected NO_VALUE to be a path" error. ... View more

Lots of great suggestions on Import but it would be very helpful if we could include a command in APOC that exports the data in a CSV format, to the browser, in a table form, with the attribute names in row 1 with the data in all the rows after. As we roll out to users, they all seem to want to use their own tools (Stata, R etc ) but all speak CSV. This should be runnable and retrieveable using BOLT. Not to the output file directory. Back to the users desktop. Any way that could be included as an option ? ... View more

I created a new database. I had installed APOC and the Graph DS Lib plugins for the previously created database. Now I get a caution triangle and it shows the pop info window that says: This plugin is not installed in these local graphs: Name of my new DB To install it for individual graphs go to [Manage] -> [Plugins] and click install But I can't find [Manage] anywhere! I clicked on all the icons in the left side of the Desktop and Browser window. I looked at all the menu items (I'm on a Mac). This is with Desktop 1.3.10 I usually find the Neo4J GUI easy to use, but not this time! (Later).... I finally figured it out: I need to click on the "+ Add Plugin" button that's in the "Graph Apps" section. So one minor GUI bug is that "[Manage]" is wrong. I added the plugin for APOC and it worked. But I discovered a second minor GUI bug. If I stop the newly created DB and start the old one, then I get a warning triangle over the Graph DS Lib Plugin. However, the popup error says: This plugin is not installed in these local graphs: EMPTY LINE To install it for individual graphs go to [Manage] -> [Plugins] and click install which sort of makes sense because Graph DS Lib has been installed for the old DB. Note there is no warning triangle for APOC. I suspect the warning states didn't get reset when I started the old DB. ... View more
