I thought I had this faster but this is 22seconds

match (message:Message)
WHERE message.creationDate > 20111021192109382
and
size((message)<-[:LIKES]-()) > 400
with message order by size((message)<-[:LIKES]-()) > 400 limit 100
match (message:Message)-[:HAS_CREATOR]->(creator:Person)
RETURN
message.id,
message.creationDate,
creator.firstName,
creator.lastName,
size((message)<-[:LIKES]-()) as likeCount
ORDER BY
likeCount DESC,
message.id ASC

With index on :Message(creationDate), I was able to rewrite the query and get results in 110 seconds instead of 429

MATCH (message:Message)
WHERE message.creationDate < 20120501000000000
with toFloat(count(message)) as allMessages
match (message:Message)
WHERE message.creationDate < 20120501000000000
WITH allMessages, toFloat(count(message)) AS messageCount, message.creationDate/10000000000000 AS year, floor(avg(message.length)) AS averageMessageLength,message:Comment AS isComment,
sum(message.length) AS sumMessageLength,
CASE
WHEN message.length < 40 THEN 0
WHEN message.length < 80 THEN 1
WHEN message.length < 160 THEN 2
ELSE 3
END AS lengthCategory
return year, isComment, lengthCategory, messageCount, averageMessageLength, sumMessageLength, toFloat(messageCount/allMessages) as pctMessages;

Added index on :Post(creationDate)

MATCH (p:Person {id: 19791209310731})

call apoc.path.subgraphNodes(p, {maxLevel:5, relationshipFilter:'KNOWS'})

match

RETURN

tag.name,
count(DISTINCT message) AS messageCount
ORDER BY
