使用AND运算符按多个单词搜索

Question

这很有魅力：

        Client client = new TransportClient().addTransportAddress(new InetSocketTransportAddress("localhost", 9300));

        FuzzyQueryBuilder fuzzyQueryBuilder = QueryBuilders.fuzzyQuery("field", "word_1");
        fuzzyQueryBuilder.fuzziness(Fuzziness.AUTO);

        SearchResponse response = client.prepareSearch("ts_index")
                                        .setTypes("service")
                                        .setQuery(fuzzyQueryBuilder)
                                        .setFrom(0).setSize(60).setExplain(true)
                                        .execute()
                                        .actionGet();
        SearchHit[] results = response.getHits().getHits();

但如果我想按多个单词搜索，它将不返回任何内容，例如：

FuzzyQueryBuilder fuzzyQueryBuilder = QueryBuilders.fuzzyQuery("field", "word_1 word_2");

当我使用CURL时，我通过将运算符添加到我的JSON属性来解决这个问题：

卷曲-XGET“http://localhost:9200/_search“-d”{“查询”：{“匹配”：{“字段”：{“查询”：“word\u 1 word\u 2”，““模糊性”：“自动”，““运算符”：“和”}}}}}”

我如何在Java中实现这一点？

Answer 1

您可以尝试使用枚举以动态方式构建它：

 public enum MultiQueryBuilder {

  OPERATOR_AND {
    @Override
    public QueryBuilders createQuery(String field, String multiWord) {
    String[] words = multiWord.split("\\s+");
    QueryBuilder queryBuilder = QueryBuilder.boolQuery();
    for(String word : words){
     queryBuilder.must(QueryBuilders.fuzzyQuery(field, word));
    }    
    return queryBuilder;
},

 OPERATOR_OR {
    @Override
    public QueryBuilders createQuery(String field, String multiWord) {
    String[] words = multiWord.split("\\s+");
    QueryBuilder queryBuilder = QueryBuilder.boolQuery();
    for(String word : words){
     queryBuilder.should(QueryBuilders.fuzzyQuery(field, word));
    }    
 return queryBuilder;
};

 public abstract Querybuilders createQuery(String field, String multiWord);
}

你只需要这样称呼它：

FuzzyQueryBuilder fuzzyQueryBuilder = QueryBuilders
    .fuzzyQuery(MultiQuerybuilder
    .valueOf(OPERATOR_AND)
    .createQuery("field", "word_1 word_2"));

我相信这是可能的，对于和，必须；对于或，应该：

 QueryBuilder qb = QueryBuilders.boolQuery()
                .must(QueryBuilders.fuzzyQuery("field", "word_1"))
                .must(QueryBuilders.fuzzyQuery("field", "word_2"));
