Is it possible to order and filter by relation in neo4j ? for example : I have gardien and kid with relations (father,mother,brother, sister) and I want to list gardiens and kids with their relationships with this type of filter: if the gardien is th...
In my neo4j machine I have limited memory but data/indexes easily exceed available memory. Machine Physical RAM: 64G. Output of bin/neo4j-admin memrec --database=graph.db Based on the above, the following memory settings are recommended: dbms.memor...

i am completely new to the neo4j but i practiced a lot to build graph models using small data sets. now i am trying to implement Q/A system using graph functions. How to add new set of question and answer to the graphs and how to retrieve answers fr...
How is the performance of UNION queries versus the MATCH/WITH/COLLECT/UNWIND strategy? The latter allows for post-union processing for sorting and processing, but I fear a performance hit in looping through the result sets. I wonder if it is better t...
I am unable to get Neo4j to load APOC. Help is appreciated... Neo4j version = 3.4.7 APOC version = 3.4.0.3 neo4j.conf has: dbms.security.procedures.unrestricted=apoc.* Neo4j starts then shuts down. The debug.log says: 2018-09-24 17:34:32.668+0000 I...
I suspect that I'm just asking a basic question in a new and less intelligent way, but is there a way of getting just the top/bottom node by value without going through an ORDER BY, collect()[..1], UNWIND? It just feels very long-winded, and somethi...
I have searched everywhere, but cannot find the answer to this. I need to create a node Config that has a Properties object with 2 key/value pairs (name and type). The keys, when queried, should end up as properties.name and properties.type. But I ca...
Simply put, I have a Spark job that's run, the output of which is a CSV. Currently, I load this CSV into Neo4j without problems. But, I'd like to do one more step: add a single node representing information about the job run to the graph that will li...
Hello everyone, where can I find information about how to use the bolt protocol? I mean, without using a driver, like if I would like to use the protocol to communicate with Neo4j directory.
Excuting the query of similarity was successuful by using this : MATCH (at1:Attrib)<-[r:ASSIGNED]-(c:Contrat)-[x:ASSIGNED]->(at2:Attrib) MERGE (at1)-[s:SIMILARITY]-(at2) And then , to display only Attribs which are working together , I worked with ...
Hello everyone, I am having some problems with the Cypher procedures. I want to return the graph that I get from executing a cypher query but I can't wrap my head around what type I need to return from my procedure method and what GraphDatabaseServic...
Why does this query return more than just the produced relationship ? Also, what does the limit clause in this query represent? I'm not sure exactly what it is limiting to 3. match p=(k:Person)-[:PRODUCED*2]-(m) where not (k)-[:PRODUCED]-(m) return p...
Greetings all! I have been struggling with what might be considered deduplication, except it's a matter of deleting similar nodes, rather than precise duplicates. Let me try and explain: I have (:Author) nodes, with [:WROTE] relationships to (:Book) ...
I am having a weird and frustrating problem. Fairly simple queries that (should) return subsets of my most numerous node label cause the browser to "timeout" and just show a completely blank white page. Configuration: Neo4j Server version: 3.4.5 (com...
