1，hotkey 索引结构

{
"properties": {
"id": {
"type": "keyword"
},
"searchInput": {
"type": "keyword"
},
"createDate": {
"type": "keyword"
},
"searchType": {
"type": "keyword"
}
}
}

2 TopHitsAggregationBuilder

//设置要查询的索引
SearchRequest request = new SearchRequest().indices("hotkey");
//构建搜索
SearchSourceBuilder sourceBuilder = new SearchSourceBuilder();
//添加搜索长度
sourceBuilder.size(0);
//添加搜索条件
sourceBuilder.query(new BoolQueryBuilder().must(QueryBuilders.termQuery("searchType", searchDto.getSourceType())));
//设置要聚合的字段以及条数
//设置该次聚合的名称 terms(args1)

// 需要返回字段的集合
String[] param = {"searchInput"};

// 对需要返回的数据包括哪些,不包括哪些,重复的只返回1条
TopHitsAggregationBuilder top1 = AggregationBuilders.topHits("top").fetchSource(param, Strings.EMPTY_ARRAY).size(1);
// 通过searchInput聚合并且聚合后返回10条数据,注意这里的size(这里代表聚合查询出多少条数据,注意这里的size要比最下面分页的size要大,因为是对聚合后的数据分页,如果不写的话默认是10)
TermsAggregationBuilder agg1 = AggregationBuilders.terms("searchInput").field("searchInput").subAggregation(top1).size(30);
//以及要聚合的字段field(args1 + ".keyword") 添加keyword是对字段进行不分词查询。

agg1.subAggregation(new BucketSortPipelineAggregationBuilder("bucket_field",null).
from((searchDto.getPageIndex() - 1) * searchDto.getPageSize()).size(searchDto.getPageSize()));
sourceBuilder.aggregation(agg1);

request.source(sourceBuilder);
SearchResponse response = null;
try {
response = elasticsearchTemplate.search(request);
} catch (Exception e) {
log.error("==========search hotkey error====", e);
}
Aggregations aggregations = response.getAggregations();

List<String> list = new ArrayList<>();
Terms terms1 = aggregations.get("searchInput");

3，kibana 查询

{"size":0,"query":{"bool":{"must":[{"term":{"searchType":{"value":"app","boost":1.0}}}],"adjust_pure_negative":true,"boost":1.0}},"aggregations":{"searchInput":{"terms":{"field":"searchInput","size":30,"min_doc_count":1,"shard_min_doc_count":0,"show_term_doc_count_error":false,"order":[{"_count":"desc"},{"_key":"asc"}]},"aggregations":{"top":{"top_hits":{"from":0,"size":1,"version":false,"seq_no_primary_term":false,"explain":false,"_source":{"includes":["searchInput"],"excludes":[]}}},"bucket_field":{"bucket_sort":{"sort":[],"from":0,"size":10,"gap_policy":"SKIP"}}}}}}
