如何在Java Elasticsearch中定居

Question

你好elasticsearch朋友我想在搜索时设置超时。因此，将Settimeout放入SearchRequestBuilder中的10s。但是每次我都会通过查询成为解析失败。我不明白为什么。

这是我的setteMout的搜索controller：

@RestController
public class SearchController {
@Autowired
@Named("es")
private Node node;
@RequestMapping(method = RequestMethod.GET, value = "/search/{query}")
public List<Hit> search(@PathVariable("query") String query){
    Client client = node.client();
    List<Hit> esData = new ArrayList<Hit>();
    SearchRequestBuilder request1 = client.prepareSearch("orange11").setTimeout("10s").setQuery(query);
    SearchResponse response1 = request1.execute().actionGet();
    System.out.println("Hits: "+response1.getHits());
    for(SearchHit hit : response1.getHits()){
        Hit hitDto = new Hit(hit.getSource());
        Map<String, HighlightField> highlightFields = hit.getHighlightFields();
        for(String s : highlightFields.keySet()){
            List<String> fragmentsDto = new ArrayList<>();
            Text [] fragments = highlightFields.get(s).fragments();
            for (Text fragment : fragments){
                fragmentsDto.add(fragment.toString());
            }
            hitDto.addField("_all", fragmentsDto);
        }
        esData.add(hitDto);
    }
    return esData;
}

}

这是例外：

查询是：

{"size" : 10, "from" : 0, "query" : { "match" : { "_all" : {"query" : "'+searchTerm+'"}}}, "highlight" : {"fields" : { "*" : {}}, "require_field_match" : false}}}

节点设置为：

        ImmutableSettings.Builder meineSettings = ImmutableSettings.settingsBuilder();
    meineSettings.put("node.name", "orange11-node");
    meineSettings.put("path.data", "/Users/lucaarchidiacono/IdeaProjects/moap2/MP3_MoapSampleBuild/data/index");
    meineSettings.put("index.store.type", "memory");
    meineSettings.put("http.enabled", false);

Answer 1

您的解码查询是这个：

{
  "size": 10,
  "from": 0,
  "query": {
    "match": {
      "_all": {
        "query": "dolore"
      }
    }
  },
  "highlight": {
    "fields": {
      "*": {}
    },
    "require_field_match": false
  }
}}

您的结尾有太多的卷发括号，应该是

{
  "size": 10,
  "from": 0,
  "query": {
    "match": {
      "_all": {
        "query": "dolore"
      }
    }
  },
  "highlight": {
    "fields": {
      "*": {}
    },
    "require_field_match": false
  }
}          <--- fix this

Answer 2

尝试一下。以毫秒而不是秒数。

GET /_search?timeout=10ms
