I have a problem with a query.I used a query for boosting documents with no
nested_objects. Now i use nested_objects and changed the query to use a
nested filter but nothing is boosted. I get the documents i expected but
with no _score changes.
Am i doing something wrong?
GET index/type/_search
{
"query": {
"function_score": {
"filter": {
"bool": {
"must": [
{
"term": {
"parent.child": "test"
}
}
]
}
},
"functions": [
{
"boost_factor": "100",
"filter": {
"nested": {
"path": "parent",
"filter": {
"bool": {
"must": [
{
"term": {
"child": "test"
}
}
]
}
}
}
}
}
],
"score_mode": "sum"
}
},
"sort": "_score",
"from": 0,
"size": 320
}
Or is it because of
A nested filter behaves much like a nested query, except that it doesn’t
accept the score_mode parameter. It can only be used in “filter context” —
such as inside a filtered query — and it behaves like any other filter: it
includes or excludes, but it doesn’t score.While the results of the nested filter itself are not cached, the usual
caching rules apply to the filter inside the nested filter.
Thanks
