张延召 commented on PHOENIX-4811:
------------------------------
I tried this,and it did,but I have a question,why can I not create this index
with (name, age) in mysql database,What is the mechanism that led me to do
this in phoenix?
> Phoenix Secondary Index isn't be used

> Key: PHOENIX-4811
> URL: https://issues.apache.org/jira/browse/PHOENIX-4811
> Project: Phoenix
> Issue Type: Bug
> Affects Versions: 4.13.1
> Environment: Operating System : centos6.9 ;
> Phoenix version : 4.13.1;
> HBase version : 1.3.1;
> Reporter: 张延召
> Priority: Major
> Labels: SecondaryIndex
> Original Estimate: 48h
> Remaining Estimate: 48h
>
> I created two indexes (not Covered Indexes):
> ^create table test(id varchar not null primary key,name varchar,age varchar
> ,sex varchar);^
> ^create local index if not exists val_test_name on test(name);^
> ^create local index if not exists val_test_age on test(age);^
> ^upsert into test(id,name,age,sex)values('myid','name','age','sex');^
> It is work to use one index:
> ^explain select name from test where name = 'name';^
> But why can't hit index when using multiple indexes？
> ^explain select name,age from test where name = 'name' and age = 'age';^
