Notice that this query only finds people who work for the same company as Sarah. If
we want to extend the search to find people who work for other companies, we need to
modify the query slightly:
START
subject=
node
:user(name=
{name}
)
MATCH
(subject)-[:INTERESTED_IN]->(interest)<-[:INTERESTED_IN]-(person),
(person)-[:WORKS_FOR]->(company)
RETURN
person.name
AS
name,
company.name
AS
company,
count
(interest)
AS
score,
collect
(interest.name)
AS
interests
ORDER BY
score
DESC
The changes are as follows:
