Support multiple rescores Detects if rescores arrive as an array instead of a plain object. If so then parse each element of the array as a separate rescore to be executed one after another. It looks like this:
"rescore"
: [ {
"window_size"
: 100,
"query"
: {
"rescore_query"
: {
"match"
: {
"field1"
: {
"query"
: "the quick brown",
"type"
: "phrase",
"slop"
: 2
}
}
},
"query_weight"
: 0.7,
"rescore_query_weight"
: 1.2
}
},
{
"window_size"
: 10,
"query"
: {
"score_mode":
"multiply",
"rescore_query"
: {
"function_score"
: {
"script_score": {&'?1>01G1G<<>6=?<!F?;<>!>49GE;66?>6=9F1G:9
"script":
"log10(doc['numeric'].value + 2)"
}
}
}
}
}
]
Rescores as a single object are still supported.
