java-high-level-rest-client提供了一种使用其代码下方显示的术语在Elasticsearch上进行搜索的方法
SearchSourceBuilder sourceBuilder = new SearchSourceBuilder();
sourceBuilder.query(QueryBuilders.termQuery("user", "kimchy"));
但是我想对多个字段进行查询,例如:“ user” =“ kimchy”和/或“ city” =“ london”。
我看到了multi-search查询和多重匹配查询,但它们没有满足我的要求。
感谢您的帮助!

尝试一下:
BoolQueryBuilder boolQueryBuilder = QueryBuilders.boolQuery();
boolQueryBuilder
.filter(QueryBuilders.termQuery("user", "kimchy"))
.filter(QueryBuilders.termQuery("city", "london"));
SearchSourceBuilder sourceBuilder = new SearchSourceBuilder();
sourceBuilder.query(boolQueryBuilder);
filter/must/should
上的BoolQueryBuilder
方法取决于您想要的上下文,如果要“或”,则可以使用should
。

可以尝试一下。
BooleanQuery.Builder booleanQuery = new BooleanQuery.Builder();
foreach (var term in (s + ',' + t).Split(','))
{
booleanQuery.add(new TermQuery(new Term("content", term)), BooleanClause.Occur.SHOULD);
}
//booleanQuery.add(new TermQuery(new Term("content", s)), BooleanClause.Occur.MUST);
//booleanQuery.add(new TermQuery(new Term("content", t)), BooleanClause.Occur.MUST);
TopDocs hits = searcher.search(booleanQuery.build(), int.MaxValue);
