Interface RankFeatureCondition

根据字段的值来排序查询结果

Example


import * as es from 'es'
let client=es.newClient('axis_esClient')
let rankFeature: es.RankFeatureCondition = {
    "field": "url_length",
    "boost": 0.1
}
let querydsl:es.Query={
    "rank_feature":rankFeature
}
let cnt = client.updateByQuery("indexName", querydsl, "newScript")
interface RankFeatureCondition {
    boost?: number;
    field: string;
    linear?: any;
    log?: any;
    saturation?: any;
    sigmoid?: any;
}
