Hi guys,
Re 5.0 Boosting Queries
https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-boosting-query.html
I'm interested in the best way to boost scores based on the importance of kinds of text (e.g. titles, comments), etc.
I'm experimenting with a mapping that uses a nested object containing 2 fields: text and weight, and I want to boost scores at query time based on the values of the weight field.
Is this possible with the "boosting" query? From results using the query below, I see that the docs that match the "positive" clause are boosted, but scores for other docs are unchanged. Am I doing something wrong?
{
"query": {
"bool": {
"must": {
"nested": {
"path": "content",
"score_mode": "avg",
"query": {
"bool": {
"must":
[
{"match": {"content.text": "aid"} }
],
"should":
{"boosting": {
"positive": {
"term" : {"content.weight": 2}
},
"negative": {
"term" : {"content.weight": 0}
},
"negative_boost": 0.5
}
}
}
}
}
}
}
}
}
I have documents with weight values of 0,1,2; the only scores affected based on my tests are those with weight 2.
Thanks!
