Hi, is there a chance to use MIN, MAX in Cypher like in the following example, or is it possible to save the rand()- value into a variable and use the variable in the same cypher- statement. MATCH (:Person)-[c:Meeting]->(q:Person) WHERE (q.att1 = 0) ...
I have neo4j version server 3.5.18 and I've installed apoc version 3.5.0.11. I think that I have correctly modified the conf file in this way dbms.directories.plugins=/Users/lx2pwnd/Desktop/dev/neo4j-community-3.5.18/plugins ... dbms.security.proce...
Hello everyone! I've been struggling to implement a trigger that adds the timestamp of a relation's creation as its property. I've seen this post and I found it really useful, where after changing the syntax to my neo4j version (Community 4.0.0) I ma...
Im trying to find similar images using approximate nearest neighbour algorithm using cosine similarity. This is the query: MATCH (p:Image) WITH {item:id(p), weights: p.vec} AS userData WITH collect(userData) AS data CALL gds.alpha.ml.ann.write({ node...
Cartesian Products lie at the heart of pretty much every query I've been troubleshooting on our Neo servers over the last nine months, however I can't find a generic solution to this one. The query is produced by query builder code in response to use...
I would like to retrieve node couples, for which both nodes only differ from each other in a single relationship (with a certain label). I have no clue how to do this :-S Any help? pointers?
Hi folks, I am interested in building a graph with some fairly rigid constraints. Some of these can be handled by the standard constraint mechansim, but some will require analysis of select nodes/relationships within the transaction scope and in som...
Neo4j Browser version: 3.2.20 Hi, I've been trying to code the above relationship between two users from the MOVIE Lens database and it gives me the following error. Can someone help? I just registered with the community so I hope I did't do anything...
Hello, I would like to learn how APOC's PageRank algorithm is implemented code-wise. I have checked its GitHub (https://github.com/neo4j-contrib/neo4j-apoc-procedures), searched all files for the keyword pagerank, but didn't find a real implementatio...
I have setup a casual cluster with 3 servers with monitoring enabled. However Neo4j_ids_in_use Metrics shows different number in each server for nodes , Relationships and Properties. I was expecting the same number of nodes on each server. Or is this...
Under Members -> Query Performance there are two columns called Compile (avg) and Execute (avg). What are the units for these two? I am assuming ms, but without a specified unit it is hard to tell.
I'm trying to run some queries on the date I've imported (while the rest are being imported) into neo4j but I'm getting the following error: Something went wrong: "Error: Reference.set failed: First argument contains a string greater than 10485760 ut...
Anyone seen problems with apoc.merge.node and fulltext index with a custom analyzer? My custom analyzer works perfectly with the cypher merge statement but the same merge with apoc seems to skip the index or at least the analyzer. Tested in neo 3.5.1...
Hi We've created nodes such as p:Person for around 50 persons in a CSV file and what we currently want is to split up the property of lets say Company to create their own nodes for this, and make relationships between. The current dataset (CSV) looks...
When re-executing queries in Neo4j Desktop, the status text on the bottom of the query frame (e.g. "Started streaming 1 records after 214 ms and completed after 394 ms.") will not be refreshed, always showing the status of the first execution Best Re...
