我正在从名为replacement_local100的Elastic Search索引中获取文档。我两次查询相同的索引。
第一次->基于code作为输入，得到link_ids的列表。
第二次->基于List of Link IDs（来自第一个查询），我得到了不同的数据，我也正在使用过滤器。
当我调用第二个查询时，出现错误：

以下我用于从ElasticSearch索引中获取文档的Java代码。
private final String INDEX = "replacement_local100";
private final String TYPE = "doc";
private RestHighLevelClient restHighLevelClient;
private ObjectMapper objectMapper;
public ReplacementDao( ObjectMapper objectMapper, RestHighLevelClient restHighLevelClient) {
this.objectMapper = objectMapper;
this.restHighLevelClient = restHighLevelClient;
}
public List<Replacement> getReplacementByCode(String code, String regionId, String countryCode, String companyId){
System.out.println("replacement service...."+code);
try {
if (restHighLevelClient != null) {
restHighLevelClient.close();
}
} catch (final Exception e) {
logger.info("Error closing ElasticSearch client: ");
}
try {
restHighLevelClient = new RestHighLevelClient(
RestClient.builder(
new HttpHost("localhost", 9200, "http"),
new HttpHost("localhost", 9201, "http")));
} catch (Exception e) {
logger.info(e.getMessage());
}
SearchRequest searchRequest = new SearchRequest(INDEX);
SearchRequest searchRequest2 = new SearchRequest(INDEX);
searchRequest.types(TYPE);
SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder();
SearchSourceBuilder searchSourceBuilder2 = new SearchSourceBuilder();
QueryBuilder qb = QueryBuilders.matchQuery("code", code);
searchSourceBuilder.query(qb);
searchSourceBuilder.size(50);
searchRequest.source(searchSourceBuilder);
SearchResponse searchResponse1 = null;
try {
searchResponse1 = restHighLevelClient.search(searchRequest);
} catch (IOException e) {
e.getLocalizedMessage();
}
SearchHit[] searchHits1 = searchResponse1.getHits().getHits();
System.out.println("Hits size--->"+searchHits1.length);
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((Integer) sourceAsMap1.get("link_id"));
linkIDList.add(linkId);
}
System.out.println("Link ID List Size --->"+linkIDList.size());
for(Replacement link_id:linkIDList) {
System.out.println("Link ID List --->"+link_id.getLink_id()+" Type--->"+link_id.getType());
}
QueryBuilder qb2=null;
List<Integer> link_id_array=new ArrayList<Integer>();
for(Replacement link_id:linkIDList) {
link_id_array.add(link_id.getLink_id());
}
qb2 = QueryBuilders.boolQuery()
.must(QueryBuilders.termQuery("id", link_id_array))
.filter(QueryBuilders.matchQuery("product_link_type", "replacement"));
searchSourceBuilder2.query(qb2);
searchSourceBuilder2.size(50);
searchRequest2.source(searchSourceBuilder2);
System.out.println("Request 2 --->"+searchRequest2);
SearchResponse searchResponse2 = null;
try {
searchResponse2 = restHighLevelClient.search(searchRequest2); // Am getting error on this line
} catch (IOException e) {
e.getLocalizedMessage();
}
List<Replacement> replacementList=new ArrayList<Replacement>();
SearchHit[] searchHits2 = searchResponse2.getHits().getHits();
for (SearchHit hit2 : searchHits2) {
Map<String, Object> sourceAsMap2 = hit2.getSourceAsMap();
replacement=new Replacement();
replacement.setId(sourceAsMap2.get("id").toString());
replacement.setCode(sourceAsMap2.get("code").toString());
replacementList.add(replacement);
}
答案 0 :(得分：3)
问题是这一行：
.must(QueryBuilders.termQuery("id", link_id_array))
由于要传递ID列表，因此您需要使用terms查询
.must(QueryBuilders.termsQuery("id", link_id_array))
