Custom document scorer

Elastic Stack Elasticsearch
1

Hello,

I was wondering if it is possible to get back the highest scoring index for
a field within an array.
Let's say I have the following document:

{
"tweet" : {
"message" : "some arrays in this tweet...",
"tags" : ["elasticsearch", "wow"],
"lists" : [
{
"name" : "cool_list1",
"description" : "very cool"
},
{
"name" : "cool_list2",
"description" : "cool"
}
]
}
}

I'm searching for: tweet.lists.description:cool

Now I would like to get back the array index with the highest relevancy.
This would be the second one where it says "cool". Is there a way for me to
implement this?

I have been using Solr for a long time now, but I really like how easy ES
works and the fantastic scalability features. However, I am missing the
advanced extendibility possibilities that I have with Solr. Or am I missing
something?

Kind regards,

Jeroen

In this case, you would need to break each item in the list into a different
document. What feature in Solr allows you to do it?

I do this in Solr by using a custom similarity class.

You can plug in your own Lucene similarity implementation to elasticsearch.
Not properly documented yet, but ping and I can help once you want to do it.
