替换 java api 客户端中的 SearchSourceBuilder class

Question

I am migrating a java application from elastic search high level client to java api client. There is a SearchSourceBuilder class in elastic search java high level client. But I couldn't find any corresponding class in java api client. Can someone help on this? Old code snippet is as below.

BoolQuery.Builder builder = QueryBuilders.bool();
SearchSourceBuilder sourceBuilder = new SearchSourceBuilder();
sourceBuilder.query(boolQueryBuilder);

Answer 1

You can write bool query as shown below in new Java client. as far as i know SearchSourceBuilder is not available in new client.

Query termQuery = TermQuery.of(t -> t.field("field_name").value("search_value"))._toQuery();

SearchRequest sr = SearchRequest.of(r -> r.query(q -> q.bool(b -> b.must(termQuery))));
