Elasticsearch内部命中响应

Question

这是我的查询函数:

public  List<feed> search(String id) throws IOException {    
Query nestedQuery = NestedQuery.of(nq ->nq.path("comment").innerHits(InnerHits.of(ih -> ih)).query(MatchQuery
.of(mq -> mq.field("comment.c_text").query(id))._toQuery()))._toQuery();
Query termQueryTitle = TermQuery.of(tq -> tq.field("title").value(id))._toQuery();
Query termQueryBody = TermQuery.of(tq -> tq.field("body").value(id))._toQuery();
Query boolQuery = BoolQuery.of(bq -> bq.should(nestedQuery, termQueryBody, termQueryTitle))._toQuery();
SearchRequest searchRequest = SearchRequest.of(s -> s.index(indexName).query(boolQuery));
var response = elasticsearchClient.search(searchRequest, feed.class);
for (var hit : response.hits().hits()){
System.out.println("this is inner hit response: " + (hit.innerHits().get("comment").hits().hits()));  }
List<Hit<feed>> hits = response.hits().hits();
List<feed> feeds = new ArrayList<>();
feed f=null;
for(Hit object : hits){
f = (feed) object.source();
feeds.add(f); }   
return feeds;
}

我已经添加了这个代码

for (var hit : response.hits().hits()){
System.out.println("this is inner hit response: " + (hit.innerHits().get("comment").hits().hits()));  }

如果它找到2条记录，它会给我2条记录的引用，但不会显示实际的记录，就像它的输出一样，如果它在内部命中找到2条记录:

this is inner hit response [co.elastic.clients.elasticsearch.core.search.Hit@75679b1a]
this is inner hit response [co.elastic.clients.elasticsearch.core.search.Hit@1916d9c6]

谁能帮我输入实际的记录

Answer 1

这对我来说是正确的:

for (var hit : response.hits().hits()) {
var innerHits = hit.innerHits().get("comment").hits().hits();
for (var innerHit : innerHits) {
JsonData source = innerHit.source();
String jsonDataString = source.toString();
System.out.println("Matched comments"+jsonDataString);
}
}

Answer 2

我创建了一个类Comment，属性为"c_text"并在列表中添加注释之前进行了强制转换。

var comments = new ArrayList<Comment>();
for (var hit : response.hits().hits()) {
comments.addAll(hit.innerHits().get("comment").hits().hits().stream().map(
h -> h.source().to(Comment.class)
).collect(Collectors.toList()));
}
System.out.println(comments);
