Hi, Very happy to join the community. I understand in Neo4j 4, we are able to switch to another database in Neo4j Browser. My question is how can we merge 2 or more databases? Say I have A.db, B.db, and C.db, how can we combine A, B, and C to generat...

Dear Everyone, I am new to NEO4J and reading as much as possible. I have been searching for information about linking to external files such as doc files. I am building a personal administration database with a Timeline tree and would like to have no...
Hello team , Please help me in validating the cypher query for bulk deletion of data under specific label: call apoc.periodic.iterate("MATCH (n:SITE) return n", "DETACH DELETE n", {batchSize:1000}) yield batches, total return batches, total Regards A...
I have tried profiling the following simple cypher query: profile match (a:A)-[r:R]->(b:B) return * The plan is as follows: NodeByLabelScan. According to neo4j statistics, it is clear the first step, NodeByLabelScan cardinality can be estimated wi...
Hi, I am using Neo4j full text search index. I am playing with a query in one of the example in Christophe Willemsen's demo. My use case is as follows - User has friends(other user nodes) and a user owns books. Through the UI, a user searches another...
Take this example query, which is a fragment of a larger query. WITH ['foo', 'bar', 'baz'] AS theList, 42 AS someVal UNWIND (CASE theList WHEN [] THEN [null] ELSE theList END) AS l CREATE (w:Word {content: l}) WITH DISTINCT someVal AS sv2 RETURN sv2;...
Dear Everyone, I am attempting to upgrade from version 3.5.13 to 4.0. I keep getting the error: Could not find a compatible version of graph algorithm. I have read the log file, but most of it is outside of my knowledge base at the moment. I hav past...
Hello, I was earlier able to connect to Neo4j Bloom 1.2.0 while using Neo4j DB 3.5.14. Suddenly, it stopped working. When I open Neo4j bloom, it displays blank screen. Below is some information: neo4j desktop version - 1.2.4browser version - 4.0.3Neo...
Hi community, I've got a weird problem using apoc.cypher.run. When I pass the cypher variable it runs as expected within a few ms. But matching a node and using passing a "cypher-property" to the procedure slows it down to nearly 5 sec. Even if I use...
Hello, I am using neo4j full text search. I manually create the full text search index and the query works fine as well. The query is run through SDN (@Query) However, I also have integration test to tests the functionality. These tests run the query...
My current code below runs for a long time for 100001 alias nodes: CALL apoc.periodic.iterate("MATCH (a:alias) RETURN a", "Match path=((a) -- (c1:citation) -[p1]-> (t:BIOTERM) <-[p2]- (c2:citation) -- (b:alias)) WHERE id(a) < id(b) AND id(c1) <> i...
I want to create an graph using ne04j which gives me a graph of the terms included in javascript array along with relative terms pointed to terms, and no duplicates if 2 terms have a common relative term it should point to a single relative term { "...
