elasticsearch,elasticsearch-jest,Spring,Spring 如何使用jest客户端或传输客户端在弹性搜索中使用三个表单字段进行搜索
三种形式的字段表示经验、技能和位置我想用技能或技能搜索，或用位置或技能搜索，或用经验搜索。但这里的技能是苛刻的。我只写用技能搜索，但我想用上面提到的不同方式搜索。请帮助我 这里我搜索技能..代码 //客户端类Spring 如何使用jest客户端或传输客户端在弹性搜索中使用三个表单字段进行搜索,spring,

公共列表搜索偶（字符串技能）
{
列表=新的ArrayList（）；
JestClient=ElasticClient.getClient（）；
SearchSourceBuilder SearchSourceBuilder=新的SearchSourceBuilder（）；
searchSourceBuilder.query（QueryBuilders.queryString（“*”+skills+“*”）；
Search Search=（Search）new Search.Builder（searchSourceBuilder.toString（））
.addIndex（“eix”）
.addType（“条款”）
.build（）；
尝试
{
SearchResult=client.execute（搜索）；
List list1=result.getHits（SearchModel.class）；
如果（！list1.isEmpty（））
{
对于（int i=0；i如果您只需要技能：
GET /hotlist/candidate/_search
{
"query": {
"bool": {
"must": [
{
"query_string": {
"default_field": "skills",
"query": "java,html"
}
}
]
}
}
}
因此，在Java中，API应该是：
searchSourceBuilder.query(QueryBuilders.boolQuery()
.must(QueryBuilders.queryStringQuery(skills).defaultField("skills"));
如果您需要技能和工作地点：
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))
);
searchSourceBuilder.query(QueryBuilders.boolQuery()
.must(QueryBuilders.queryStringQuery(skills).defaultField("skills"))
.must(QueryBuilders.termQuery("JobLocations", jobLocations))
.must(QueryBuilders.termQuery("Experience", experience))
);
如果您想要全部：
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))
);
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"))
);
}
//[...]
公共列表搜索偶（字符串技能、字符串经验、字符串位置）
{
列表=新的ArrayList（）；
JestClient=ElasticClient.getClient（）；
SearchSourceBuilder SearchSourceBuilder=新的SearchSourceBuilder（）；
如果（！StringUtils.isEmpty（经验））{
如果（！StringUtils.isEmpty（位置））{
//地点和经验都很丰富
searchSourceBuilder.query（QueryBuilders.boolQuery（）
.must（QueryBuilders.queryStringQuery（skills.defaultField（“skills”））
.must（QueryBuilders.termQuery（“作业位置”，作业位置））
.must（QueryBuilders.termQuery（“经验”，Experience））
);
}否则{
//只有经验存在
searchSourceBuilder.query（QueryBuilders.boolQuery（）
.must（QueryBuilders.queryStringQuery（skills.defaultField（“skills”））
.must（QueryBuilders.termQuery（“经验”，Experience））
);
}
}如果（！StringUtils.isEmpty（位置））为else{
//只有位置存在
searchSourceBuilder.query（QueryBuilders.boolQuery（）
.must（QueryBuilders.queryStringQuery（skills.defaultField（“skills”））
.must（QueryBuilders.termQuery（“作业位置”，作业位置））
);
}否则{
//地点和经验都不存在
searchSourceBuilder.query（QueryBuilders.boolQuery（）
.must（QueryBuilders.queryStringQuery（skills.defaultField（“skills”））
);
}
//[...]
使用下面定义的bool查询
if (!StringUtils.isEmpty(experience) && !StringUtils.isEmpty(location))
searchSourceBuilder.query(QueryBuilders.boolQuery().must(QueryBuilders.queryString("*"+skills+"*")).
must(QueryBuilders.queryString("*"+experience+"*").defaultOperator("AND"))
.must(QueryBuilders.queryString("*"+location+"*").defaultOperator("AND")));
else if (!StringUtils.isEmpty(experience))
searchSourceBuilder.query(QueryBuilders.boolQuery().must(QueryBuilders.queryString("*"+skills+"*")).
must(QueryBuilders.queryString("*"+experience+"*").defaultOperator("AND")));
else if (!StringUtils.isEmpty(location))
searchSourceBuilder.query(QueryBuilders.boolQuery().must(QueryBuilders.queryString("*"+skills+"*")).
must(QueryBuilders.queryString("*"+location+"*").defaultOperator("AND")));
else
searchSourceBuilder.query(QueryBuilders.boolQuery().must(QueryBuilders.queryString("*"+skills+"*")));
我没有得到结果共享映射请我得到[]（null）值我希望你共享映射。GET/index/type/_mappinghotlist是index，type是candidate我没有得到结果我得到[]（null）值你能共享你类型的映射吗？比如{“hotlist”：{“alias”：{}，“mappings”：{“candidate properties”：{“CurrentJobTitles”：“类型”：“字符串”}，“经验”：“类型”：“字符串”}，“工作地点”：{“类型”：“字符串”}，“成就”：{“类型”：“字符串”}，“城市”：{“类型”：“字符串”}，“国家”：“类型”：“字符串”}，“热列表”：“属性”：“别名”：“类型”：“对象”}，“映射”：{“属性”：{“候选”：{“属性”：{“属性”：{“属性”：{“属性”：{“属性”：经验”：{“属性”：{“type”：{“type”：“string”}}}，我可以发布整个服务类来修复它吗？，我再次得到空值
