Question

这就像一个魅力：

        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();

但如果我想用多个单词进行搜索，则不会返回任何内容，例如：

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

当我使用 CURL 时，我已通过将<{1}}添加到 JSON 属性来解决此问题：

curl -XGET“http://localhost:9200/_search” - d“{\”query \“：{\”match \“：{\”field \“：{\”query \“：\”word_1 word_2 \“ ，\ “模糊\”：\ “AUTO \”，\ “操作符\”：\ “和\”}}}}

如何在Java中实现这一目标？

Answer 1

我认为，对于AND，must和对于OR：{/ 1> should，这是可能的

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

Answer 2

您可以尝试使用enum：

以动态方式构建此内容

 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);
}

你只需要这样打电话：

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

使用AND运算符搜索多个单词
