searchSourceBuilder.query(functionScoreQueryBuilder)
.sort("_score", SortOrder.DESC)
.sort("heat", SortOrder.DESC);
SearchRequest searchRequest = new SearchRequest(elasticSearchIndexConfig.getArticleSearchIndexName());
searchRequest.types(EsConstant.DEFAULT_TYPE);
searchRequest.source(searchSourceBuilder);
List searchResults = kittyRestHighLevelClient.search(searchRequest, ArticleDocument.class);
searchResults.forEach(doc -> {
System.out.println(doc.getId() + " " + doc.getType() + " " + doc.getHeat());
});
}
scoreScript 就是控制权重的脚本，也就是一段代码（脚本默认是 groovy），是不是方便的多。 （编辑：应用网_阳江站长网）
