该项目主要是为了熟悉sql的人员能够很方便的进行elasticsearch数据的查询，降低学习成本。
##目前项目可以支持的查询如下：
//String sql = "filter:select state,city,count(distinct account_number) as count from bank where gender='M' and age>10 group by state,city";
//String sql = "filter:select state,city,sum(balance) as total from bank where gender='M' and age>10 group by state,city";
//String sql = "filter:select state,avg(balance) as total from bank where gender='M' and age>20 group by state";
//String sql = "filter:select state,max(balance) as total from bank where gender='M' group by state";
//String sql = "query:select * from bank where gender='M' and age>30";
//String sql = "query:select * from bank where gender='M' and age in(30,31,32)";
//String sql = "query:select * from bank where gender='M'";
//String sql = "query:select * from bank where id=9BnH0MToTvWMHwikTb-uhA";
//String sql = "query:select * from bank where (gender='M' and age>=40) or (balance>40000)";
//String sql = "query:select * from bank where (gender='M' and age>=40) or (balance between 40000 and 44000)";
//String sql = "query:select * from bank where (gender='M' and age>=40) or (balance>40000) limit 10";
//String sql = "query:select * from bank where gender='M' and age>=30 and (balance between 40000 and 44000)";
//String sql = "query:select * from bank where gender='M' and age>=30 and (balance between 40000 and 44000) and state in('id','wy')";
//String sql = "query:select state,max(balance) from bank where gender='M' and age>=30 and state in('id','wy') group by state";
//String sql = "query:select * from bank where firstname like '%beck%'";
//String sql = "query:select * from bank where gender='M' and (age>=30 and age<35)";
//String sql = "select sum(who.s) from events where context.channlid.s in(1,2,3,4) and context.serverid.s in('s1','s2') and what.s='item' group by context.serverid.s";
//String sql = "select * from bank.account order by age desc,account_number asc";
//------------------------------------------------------------------------------
//String sql = "select stats(balance) from bank.account group by age";
//String sql = "select stats(balance) from bank.account group by state,age[*-20|20-25|25-30|30-35|35-40|40-*]";
//String sql = "select stats(balance) from bank.account group by (age[*-20|20-25|25-30|30-35|35-40|40-*]),(state)";
//String sql = "select stats(balance) from bank.account group by (state,age[*-20|20-25|25-30|30-35|35-40|40-*]),(city)";
//String sql = "select account_number,age,balance from bank where age>25";
//String sql = "select account_number,age,balance from bank where age>25 order by balance desc";
//----------------------------------------------------------------------------------------
//String sql = "select stats(balance) from bank2.account2 group by age[histogram-5]";
//String sql = "select stats(balance) from bank2.account2 group by state,age[histogram-5]";
//String sql = "select stats(balance) from bank2.account2 group by createtime[datehistogram-2day]";
//String sql = "select stats(balance) from bank2.account2 group by state,createtime[datehistogram-2day]";
##测试数据导入
路径：/com/es/api/test/accounts.json
##执行测试：
* /com/es/api/test/BankMapping.java 创建index ，根据需求修改index和type
* /com/es/api/test/BankContentIndex.java 根据需求修改index和type，已经accounts.json路径
* 其他测试类可自行修改之后测试
##ElasticSearch - JAVA API 测试用例
/com/es/sql/query/TestQuery.java
##已经支持功能如下：
count
count(distinct ..)
sum
max
avg
min
stats
between ... and ...
like
in
not in
=
!=
>
>=
<
<=
id查询
自定义查询结果维度 select a,b,c,d from ....
多层group :实例 group by a,b,c,d
多组group :实例 group by (a,b),(c,d),(e,f)
range group:实例 group by age[*-20|20-25|25-30|30-35|35-40|40-*]
histogram :实例 group by age[histogram-5]
datehistogram ：实例 createtime[datehistogram-2day]
