I am a newbie to ES.
My goal is to compute recommendation music list for a user.
The commendation music is simply musics which the user`s friends listened
For that, I have added about 10,000,000 documents as following mapping.
Then, I have searched as following.
I expected search cost as "O(log n * friend count of '2344')" and then
facet computing cost on searched friends docs.
But when I run above query, OutOfMemory occurs as following.
query[id:2324],from,size: Query Failed [Failed to execute main
query]]; nested: ElasticSearchException[java.lang.OutOfMemoryError: Java
heap space]; nested: ExecutionError[java.lang.OutOfMemoryError: Java heap
space]; nested: OutOfMemoryError[Java heap space];
Who can I help me? Please give me some advice.
Thanks for reading.
