能够使用以下Java代码从elasticsearch中获取与我的输入代码ABC-123匹配的文档。但是现在,我想在这里再添加一个条件/过滤器,
我想获取所有匹配的代码ABC-123,而Type只是Reg

SearchRequest searchRequest = new SearchRequest(INDEX);
searchRequest.types(TYPE);
SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder();
SearchSourceBuilder searchSourceBuilder2 = new SearchSourceBuilder();
QueryBuilder qb=QueryBuilders.matchQuery("code", code);
searchSourceBuilder.query(qb);
searchRequest.source(searchSourceBuilder);
SearchResponse searchResponse1 = null;
try {
     searchResponse1 = restHighLevelClient.search(searchRequest);
} catch (IOException e) {
    e.getLocalizedMessage();
}
SearchHit[] searchHits1 = searchResponse1.getHits().getHits();
Replacement linkId = null;
Replacement replacement = null;
List<Replacement> linkIDList=new ArrayList<Replacement>();
for (SearchHit hit1 : searchHits1) {
    linkId = new Replacement();
     Map<String, Object> sourceAsMap1 = hit1.getSourceAsMap();
     linkId.setLink_id(sourceAsMap1.get("code"));
     linkIDList.add(linkId);
}

请在下面找到我的数据。
id      link_id         code            Type
1001    2001            ABC-123         Reg
1002    2002            ABC-345         Reg
1003    2003            ABC-123         Act
1004    2004            ABC-123         Reg

如果尝试搜索ABC-123,则仅期望
id      link_id         code            Type
1001    2001            ABC-123         Reg
1004    2004            ABC-123         Reg

它,不应该考虑以下记录。因为它的类型是Act
id      link_id         code            Type
1003    2003            ABC-123         Act

任何人都可以有任何想法,我如何在我的Java代码中添加filter。 ?

最佳答案

您需要将约束包装在bool/must/filter查询中,如下所示:

QueryBuilder qb = QueryBuilders.boolQuery()
    .must(QueryBuilders.matchQuery("code", code))
    .filter(QueryBuilders.termQuery("Type", "Reg"));
searchSourceBuilder.query(qb);

关于java - 如何在QueryBuilders.matchQuery()中添加过滤器以基于过滤器获取一些匹配的文档,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/50904856/
