Hi, after publishing this graphgist http://gist.neo4j.org/?05d92f567adbe971afc5 , Michael suggested to change the pattern and providing a profile.
This is the result:
The query is
{
"query" : "match
(j:jurt)-[:HAS_TERM]->()-[:BT*0..]->(t:term)-[:BT*0..1]->(t2:term
{name:{termname}}) return t.name, count(distinct j) as count order by count
desc limit 10",
"params":
{"termname" : "Eurovoc"}
}
and mydomain:7474/db/data/cypher?profile=true returns after 15 secs (the
pattern with (j:jurt)-[:HAS_TERM|BT*0..]->(t:term) took 20 sec)
