java api 检索elasticsearch数据
您可以使用terms查询来实现这个要求。具体的查询DSL如下:
```
{
"query": {
"terms": {
"_source": [
"3",
"4",
"5"
],
"boost": 1.0
}
}
}
```
在Java API中,您可以使用以下代码实现:
```java
SearchRequest searchRequest = new SearchRequest("your_index");
SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder();
TermsQueryBuilder termsQueryBuilder = QueryBuilders.termsQuery("_source", "3", "4", "5");
searchSourceBuilder.query(termsQueryBuilder);
searchRequest.source(searchSourceBuilder);
SearchResponse searchResponse = client.search(searchRequest, RequestOptions.DEFAULT);
```
其中,client是您的Elasticsearch客户端对象。请注意,terms查询默认情况下是不会被分析器分析的,所以如果您的字段是分词的,那么您需要在查询时手动指定分析器。
