spring - 如何使用 jest 客户端或传输客户端在 Elasticsearch 中使用三个表单字段进行搜索

Question

三个表单字段意味着经验和技能以及位置我想搜索技能或技能位置或技能经验..但这里技能是强制性的..我只写搜索技能但我想搜索不同的如上面提到的请帮帮我

我在这里搜索技能..代码

//客户端类

public class ElasticClient 
{
private static JestClient client = null;

private ElasticClient(){

}

public static JestClient getClient()
{
    String clusterIP = "localhost";
    String port = "9200";

    //setup client
    JestClientFactory factory = new JestClientFactory();
    factory.setHttpClientConfig(new HttpClientConfig
            .Builder("http://" + clusterIP + ":" + port)
            .multiThreaded(true)
            .build());
    JestClient client = factory.getObject();

    return client;
   }

}

//模型类

 package com.elastic.model;
 import io.searchbox.annotations.JestId;
 public class SearchModel {
 @JestId
 private String _id;
 private String CurrentJobTitles;
 private String Experience;
 private String skills;

public SearchModel(String _id, String currentJobTitles, String experience,
        String skills) {
    super();
    this._id = _id;
    CurrentJobTitles = currentJobTitles;
    Experience = experience;
    this.skills = skills;
}

public String get_id() {
    return _id;
}

public void set_id(String _id) {
    this._id = _id;
}

public String getCurrentJobTitles() {
    return CurrentJobTitles;
}

public void setCurrentJobTitles(String currentJobTitles) {
    CurrentJobTitles = currentJobTitles;
}


public String getExperience() {
    return Experience;
}

public void setExperience(String experience) {
    Experience = experience;
}

public String getSkills() {
    return skills;
}


public void setSkills(String skills) {
    this.skills = skills;
}


@Override
  public String toString() {
  return  
  "_id='" + _id + '\'' + 
  ", CurrentJobTitles='" + CurrentJobTitles + '\'' +
  ", Experience='" + Experience + '\'' +
  ", skills='" + skills + '\''

   ;

  }
  }

// Controller 类

 @Controller
 public class SearchController {    

 @RequestMapping(value = "/doSearch.htm", method = RequestMethod.POST)
 public List<SearchModel> getMessages(@RequestParam("skills") String   skills, Model model)
 {
 System.out.println(skills);
 SearchResource search = new SearchResource();
 List<SearchModel> list = new ArrayList<SearchModel>();
 list = search.searchCouple(searchKey);
 System.out.println(list);
 model.addAttribute("list",list);
 return list;
}
}   

//服务类

public List<SearchModel> searchCouple(String skills)
{
    List<SearchModel> list = new ArrayList<SearchModel>();
    JestClient client = ElasticClient.getClient();


    SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder();
    searchSourceBuilder.query(QueryBuilders.queryString("*"+skills+"*"));


    Search search = (Search) new Search.Builder(searchSourceBuilder.toString())
    .addIndex("eix")
    .addType("articles")
    .build();

    try 
    {
        SearchResult result = client.execute(search);
        List<SearchResult.Hit<SearchModel, Void>> list1 = result.getHits(SearchModel.class);

        if(!list1.isEmpty())
        {
            for(int i=0; i<list1.size(); i++)
            {
                Hit<SearchModel, Void> p = list1.get(i);
                SearchModel e = p.source;
                list.add(e);
                System.out.println(list);
            }
        }

    } catch (Exception e) {
        e.printStackTrace();
    }
    finally {
        client.shutdownClient();
    }

    return list;
}

Answer 1

如果你只想要技能:

GET /hotlist/candidate/_search
{
    "query": {
        "bool": {
            "must": [
               {
                   "query_string": {
                            "default_field": "skills",
                            "query": "java,html"
                    }
               }
            ]
        }
    }
}

所以在 Java API 中应该是:

searchSourceBuilder.query(QueryBuilders.boolQuery()
      .must(QueryBuilders.queryStringQuery(skills).defaultField("skills"));

如果您想要技能和工作地点:

GET /hotlist/candidate/_search
{
    "query": {
        "bool": {
            "must": [
               {
                   "query_string": {
                            "default_field": "skills",
                            "query": "java,html"
                    }
               },
               {
                   "term": {
                      "JobLocations": {
                         "value": "hyd"
                      }
                   }
               }
            ]
        }
    }
}

在 Java API 中:

searchSourceBuilder.query(QueryBuilders.boolQuery()
      .must(QueryBuilders.queryStringQuery(skills).defaultField("skills"))
      .must(QueryBuilders.termQuery("JobLocations", jobLocations))
      );

如果你想要全部:

GET /hotlist/candidate/_search
{
    "query": {
        "bool": {
            "must": [
               {
                   "query_string": {
                            "default_field": "skills",
                            "query": "java,html"
                    }
               },
               {
                   "term": {
                      "JobLocations": {
                         "value": "hyd"
                      }
                   }
               },
               {
                   "term": {
                      "Experience": {
                         "value": "1"
                      }
                   }
               }
            ]
        }
    }
}

在 Java API 中:

searchSourceBuilder.query(QueryBuilders.boolQuery()
      .must(QueryBuilders.queryStringQuery(skills).defaultField("skills"))
      .must(QueryBuilders.termQuery("JobLocations", jobLocations))
      .must(QueryBuilders.termQuery("Experience", experience))
      );

所以你应该有这样的东西:

public List<SearchModel> searchCouple(String skills, String experience, String location)
{
    List<SearchModel> list = new ArrayList<SearchModel>();
    JestClient client = ElasticClient.getClient();


    SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder();

    if (!StringUtils.isEmpty(experience)) {
      if (!StringUtils.isEmpty(location)) {
        //location and experience are present
        searchSourceBuilder.query(QueryBuilders.boolQuery()
                .must(QueryBuilders.queryStringQuery(skills).defaultField("skills"))
                .must(QueryBuilders.termQuery("JobLocations", jobLocations))
                .must(QueryBuilders.termQuery("Experience", experience))
                );
      } else {
        //Only experience is present
        searchSourceBuilder.query(QueryBuilders.boolQuery()
                .must(QueryBuilders.queryStringQuery(skills).defaultField("skills"))
                .must(QueryBuilders.termQuery("Experience", experience))
                );
      }
    } else if (!StringUtils.isEmpty(location)) {
      //Only location is present
      searchSourceBuilder.query(QueryBuilders.boolQuery()
                .must(QueryBuilders.queryStringQuery(skills).defaultField("skills"))
                .must(QueryBuilders.termQuery("JobLocations", jobLocations))
                );

    } else {
      //Neither location and experience are present
      searchSourceBuilder.query(QueryBuilders.boolQuery()
                .must(QueryBuilders.queryStringQuery(skills).defaultField("skills"))
                );
    }
