Java api 实现搜索

思路参考 api 写法写Java代码　请求条件构建层次思路

private RestHighLevelClient client  = new RestHighLevelClient(RestClient.builder(HttpHost.create("http://localhost:9200")));

搜索全部记录

private RestHighLevelClient client;



//搜索全部记录
@Test
public void t1() throws IOException {
    client  = new RestHighLevelClient(RestClient.builder(HttpHost.create("http://localhost:9200")));

    //请求
    SearchRequest searchRequest = new SearchRequest("myindex");
    SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder();
    searchSourceBuilder.query(QueryBuilders.matchAllQuery());
    //日志  - 3ss this is the 19

    //只获取name字段
    searchSourceBuilder.fetchSource(new String[]{"name"},new String[]{});
    //日志   - 3ss this is the null


    searchRequest.source(searchSourceBuilder);

    //执行
    SearchResponse searchResponse = client.search(searchRequest,RequestOptions.DEFAULT);

    //看结果
    SearchHits hits = searchResponse.getHits();
    for(SearchHit key : hits.getHits()){
        log.info(key.getId()+key.getSourceAsMap().get("name")+key.getSourceAsMap().get("age"));
    }
   
}

增加规则值查某些字段

//只获取name字段
searchSourceBuilder.fetchSource(new String[]{"name"},new String[]{});
//日志   - 3ss this is the null

搜索分页

构建请求的时候增加如下代码即可

int page = 1;//几页
int size = 3;//几条
searchSourceBuilder.from((page-1)*size);
searchSourceBuilder.size(size);

全代码

//搜索全部记录
@Test
public void t1() throws IOException {
    client  = new RestHighLevelClient(RestClient.builder(HttpHost.create("http://localhost:9200")));

    //请求
    SearchRequest searchRequest = new SearchRequest("myindex");
    SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder();

    //查询全部
    searchSourceBuilder.query(QueryBuilders.matchAllQuery());
    //日志  - 3ss this is the 19

    //只获取name字段
    searchSourceBuilder.fetchSource(new String[]{"name"},new String[]{});
    //日志   - 3ss this is the null

    //分页
    int page = 1;
    int size = 3;
    searchSourceBuilder.from((page-1)*size);
    searchSourceBuilder.size(size);


    searchRequest.source(searchSourceBuilder);
    //执行
    SearchResponse searchResponse = client.search(searchRequest,RequestOptions.DEFAULT);

    //看结果
    SearchHits hits = searchResponse.getHits();

    for(SearchHit key : hits.getHits()){
        log.info(key.getId()+key.getSourceAsMap().get("name")+key.getSourceAsMap().get("age"));
    }

}

Ids 搜索


//搜索id 搜索
@Test
public void t2() throws IOException {
    //请求
    SearchRequest searchRequest = new SearchRequest("myindex");
    SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder();
    //查询全部
    searchSourceBuilder.query(QueryBuilders.idsQuery().addIds("1","3"));
    searchRequest.source(searchSourceBuilder);

    //执行
    SearchResponse searchResponse = client.search(searchRequest,RequestOptions.DEFAULT);

    //看结果
    SearchHits hits = searchResponse.getHits();
    for(SearchHit key : hits.getHits()){
        log.info(key.getId()+key.getSourceAsMap().get("name")+key.getSourceAsMap().get("age"));
    }

}

关键词搜索Match搜索

//搜索match 搜索
@Test
public void t3() throws IOException {
    //请求
    SearchRequest searchRequest = new SearchRequest("myindex");
    SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder();
    //查询全部
    searchSourceBuilder.query(QueryBuilders.matchQuery("name","is"));
    searchRequest.source(searchSourceBuilder);

    //执行
    SearchResponse searchResponse = client.search(searchRequest,RequestOptions.DEFAULT);

    //看结果
    SearchHits hits = searchResponse.getHits();
    for(SearchHit key : hits.getHits()){
        log.info(key.getId()+key.getSourceAsMap().get("name")+key.getSourceAsMap().get("age"));
    }

}

multi_match 搜索多字段搜索

//搜索multi_match 搜索 多字段搜索
@Test
public void t4() throws IOException {
    //请求
    SearchRequest searchRequest = new SearchRequest("myindex");
    SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder();
    searchSourceBuilder.query(QueryBuilders.multiMatchQuery("is","name","age"));
    searchRequest.source(searchSourceBuilder);

    //执行
    SearchResponse searchResponse = client.search(searchRequest,RequestOptions.DEFAULT);

    //看结果
    SearchHits hits = searchResponse.getHits();
    for(SearchHit key : hits.getHits()){
        log.info(key.getId()+key.getSourceAsMap().get("name")+key.getSourceAsMap().get("age"));
    }

}

复杂查询 bool查询

/**
 * 复杂查询 bool 查询  多字段查询 加 可查到可不查到should
 *
 *  @author jianghaoyu
 *
 */
@Test
public void t5() throws IOException {
    //请求
    SearchRequest searchRequest = new SearchRequest("myindex");
    SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder();
    BoolQueryBuilder bqb = new BoolQueryBuilder();
    MultiMatchQueryBuilder mmqb = QueryBuilders.multiMatchQuery("is","name","age");
    bqb.must(mmqb);
    bqb.should(QueryBuilders.matchQuery("name","is"));

    searchSourceBuilder.query(QueryBuilders.multiMatchQuery("is","name","age"));

    searchRequest.source(searchSourceBuilder);

    //执行
    SearchResponse searchResponse = client.search(searchRequest,RequestOptions.DEFAULT);

    //看结果
    SearchHits hits = searchResponse.getHits();
    for(SearchHit key : hits.getHits()){
        log.info(key.getId()+key.getSourceAsMap().get("name")+key.getSourceAsMap().get("age"));
    }

}

filter bool 复杂查询增加过滤器查询

/**
 * filter  bool 复杂查询增加过滤器查询
 *
 *  @author jianghaoyu
 *
 */
@Test
public void t6() throws IOException {
    //请求
    SearchRequest searchRequest = new SearchRequest("myindex");
    SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder();
    BoolQueryBuilder bqb = new BoolQueryBuilder();
    MultiMatchQueryBuilder mmqb = QueryBuilders.multiMatchQuery("is","name","age");
    bqb.must(mmqb);
    bqb.should(QueryBuilders.matchQuery("name","is"));

    bqb.filter(QueryBuilders.rangeQuery("ages").gte(30).lte("90"));

    searchSourceBuilder.query(bqb);

    searchRequest.source(searchSourceBuilder);

    //执行
    SearchResponse searchResponse = client.search(searchRequest,RequestOptions.DEFAULT);

    //看结果
    SearchHits hits = searchResponse.getHits();
    for(SearchHit key : hits.getHits()){
        log.info(key.getId()+" value="+key.getSourceAsMap().get("name")+key.getSourceAsMap().get("age"));
    }

}

复杂擦好像加排序

/**
 * filter  bool 复杂查询增加过滤器查询 加排序
 *
 *  @author jianghaoyu
 *
 */
@Test
public void t7() throws IOException {
    //请求
    SearchRequest searchRequest = new SearchRequest("myindex");
    SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder();
    BoolQueryBuilder bqb = new BoolQueryBuilder();
    MultiMatchQueryBuilder mmqb = QueryBuilders.multiMatchQuery("is","name","age");
    bqb.must(mmqb);
    bqb.should(QueryBuilders.matchQuery("name","is"));

    bqb.filter(QueryBuilders.rangeQuery("ages").gte(30).lte("90"));

    searchSourceBuilder.query(bqb);
    searchSourceBuilder.sort("ages");

    searchRequest.source(searchSourceBuilder);

    //执行
    SearchResponse searchResponse = client.search(searchRequest,RequestOptions.DEFAULT);

    //看结果
    SearchHits hits = searchResponse.getHits();
    for(SearchHit key : hits.getHits()){
        log.info(key.getId()+" value="+key.getSourceAsMap().get("name")+key.getSourceAsMap().get("ages"));
    }

}

searchSourceBuilder.sort("ages", SortOrder.DESC);
