Hi,
Is there a way to use a different document's field value in the script_Score query?
My use-case is I have a query which is asked by multiple users and count of the query asked by the user in this way
{
"query_popularity_per_user" : {
"u-123" : 2,
"u-456" : 1
},
"global_popularity" : 3,
"query" : "current account",
"doc_type" : "search_history"
}
And my current query looks like this
{
"function_score": {
"query": {
"multi_match": {
"query": "acc",
"fields": [
"query"
],
"minimum_should_match": "40%",
"boost": 100
}
}
},
"script_score": {
"script": {
"lang": "painless",
"source": "int local_popularity = 0;String key='query_popularity_per_user.u-123';if(doc.containsKey(key) && doc[key].size()>0){local_popularity=(int)doc[key].value;}return Math.log(1+ (0.6*local_popularity) +(0.4*doc['global_popularity'].value))"
}
}
}
}
As you can see the field query_popularity_per_user grows indefinitely as the new users who ask the same question increases. For this, to scale, I thought of adding the count of query asked by a user in a different document and use that document's field value in script_score computation when a user with userId "u-123" asks this query.
My question is, inside script_score I can access current document fields using the doc field but how to access another document's field values inside script_score
