[ElasticSearch] 中文字符串精确搜索 term 搜不到结果

    public static void termQuery(Client client, String index, String type) {

        // Query
        QueryBuilder queryBuilder = QueryBuilders.termQuery("college", "计算机学院");

        // Search
        SearchRequestBuilder searchRequestBuilder = client.prepareSearch(index);
        searchRequestBuilder.setTypes(type);
        searchRequestBuilder.setQuery(queryBuilder);

        // 执行
        SearchResponse searchResponse = searchRequestBuilder.execute().actionGet();

        // 结果
        queryResult(searchResponse);
    }

搜索college为计算机学院 原始数据中有，却搜不到结果

原始数据：

11:34:22.674 [main] INFO  com.sjf.open.api.Search - ----------hit source: id 9 source {college=计算机学院, school=西安电子科技大学, sex=boy, name=廖力生, age=21}
11:34:22.677 [main] INFO  com.sjf.open.api.Search - ----------hit source: id 2 source {college=通信学院, school=西安电子科技大学, sex=boy, name=李源一, age=19}

这个坑我用6.5 的时候踩过
这样解决的

QueryBuilder queryBuilder = QueryBuilders.termQuery("college.keyword", "计算机学院");

别的版本没有试过不太清楚

这是因为：elasticsearch 里默认的IK分词器是会将每一个中文都进行了分词的切割，所以你直接想查一整个词，或者一整句话是无返回结果的。

现在解决方式如下：

     public static void termPhraseQuery(Client client, String index, String type) {

        // Query
        BoolQueryBuilder boolQueryBuilder = QueryBuilders.boolQuery();
        boolQueryBuilder.must(QueryBuilders.termQuery("college","计"));
        boolQueryBuilder.must(QueryBuilders.termQuery("college","算"));
        boolQueryBuilder.must(QueryBuilders.termQuery("college","机"));
        boolQueryBuilder.must(QueryBuilders.termQuery("college","学"));
        boolQueryBuilder.must(QueryBuilders.termQuery("college","院"));
        // Search
        SearchRequestBuilder searchRequestBuilder = client.prepareSearch(index);
        searchRequestBuilder.setTypes(type);
        searchRequestBuilder.setQuery(boolQueryBuilder);

        // 执行
        SearchResponse searchResponse = searchRequestBuilder.execute().actionGet();

        // 结果
        queryResult(searchResponse);
    }

不知道有什么更好的办法？

试试match phrase
