Hi.
To get a score of my query, I used this painless query below.
But it doesn't work.
GET _scripts/painless/_execute
{
"script": {
"source": "_score"
},
"context": "score",
"context_setup": {
"index": "review",
"document": {
"content": "He was great. It was very professional like the Elasticsearch folks."
},
"query": {
"more_like_this": {
"fields": [
"content"
],
"like": "He was great. It was very professional like the Elasticsearch folks."
}
}
}
}
And I got this error message,
{
"error" : {
"root_cause" : [
{
"type" : "null_pointer_exception",
"reason" : null
}
],
"type" : "null_pointer_exception",
"reason" : null
},
"status" : 500
}
I don't know the reason.
What could be wrong?
