最简单的查询，匹配所有文档，给它们一个_score 1.0。
QueryBuilder qb = matchAllQuery();
QueryBuilder qb = matchQuery("field","value" );
示例：查询：QueryBuilder qb = matchQuery("name", "张三");
结果
数据:{"address":"benjing","age":"12","name":"张三2"}
数据:{"address":"benjing","age":"12","name":"aa张三3","num":12}
数据:{"address":"benjing","age":"12","name":"张爱三","num":12}
数据:{"address":"benjing","age":"12","name":"张三3"}
数据:{"address":"benjing","age":"12","name":"李宏旭 张三3","num":12}
数据:{"address":"benjing","age":"12","name":"张四","num":12}
QueryBuilder qb = multiMatchQuery(
"kimchy elasticsearch", //值
"user", "message" //字段
);示例：查询：QueryBuilder qb = multiMatchQuery("张三 12", "name","age");
结果
数据:{"address":"benjing","age":"1","name":"张三"}
数据:{"address":"benjing","age":"12","name":"张三2"}
数据:{"address":"benjing","age":"12","name":"aa张三3","num":12}
数据:{"address":"benjing","age":"12","name":"张爱三","num":12}
数据:{"address":"benjing","age":"12","name":"张三3"}
数据:{"address":"benjing","age":"12","name":"李宏旭 张三3","num":12}
数据:{"address":"benjing","age":"12","name":"王五","num":3}
数据:{"address":"benjing","age":"12","name":"张四","num":12}
数据:{"address":"benjing","age":"12","name":"王五"}
common_terms查询：一个更专业的查询，它提供了对不常见单词的更多偏好
QueryBuilder qb = commonTermsQuery("field","value");示例：查询：QueryBuilder qb = commonTermsQuery("name", "张三");
结果：
数据:{"address":"benjing","age":"1","name":"张三"}
数据:{"address":"benjing","age":"12","name":"张三2"}
数据:{"address":"benjing","age":"12","name":"aa张三3","num":12}
数据:{"address":"benjing","age":"12","name":"张爱三","num":12}
数据:{"address":"benjing","age":"12","name":"张三3"}
数据:{"address":"benjing","age":"12","name":"李宏旭 张三3","num":12}query_string查询：支持紧凑的Lucene查询字符串语法，允许您在单个查询字符串中指定AND | OR | NOT条件和多字段搜索。仅限专家用户
QueryBuilder qb = queryStringQuery("+kimchy -elasticsearch"); //value
simple_query_string：query_string语法的更简单，更健壮的版本，适合直接向用户公开
QueryBuilder qb = simpleQueryStringQuery("+kimchy -elasticsearch");//value
