> 1.create INDEX_TEST_TABLE:

> varchar not null,d varchar,e varchar, f varchar constraint pk primary
> key(a,b,c));
> 2.upsert some data into table.
> 3.create index on 'D' and 'F'
> create index INDEX_TEST_TABLE_INDEX_D on INDEX_TEST_TABLE(A,D)

> 0: jdbc:phoenix:10.20.14.35:2181> create index INDEX_TEST_TABLE_INDEX_F on
> INDEX_TEST_TABLE(A,F) include(B,C,D,E);
> 5 rows affected (0.748 seconds)
> 4.query data on 'D'
> explain select * from INDEX_TEST_TABLE where A in ('1','2','3','4','5') and D
> in ('1111','2222','3333');
> 5. it is ok:
> CLIENT PARALLEL 1-WAY SKIP SCAN ON 15 KEYS OVER INDEX_TEST_TABLE_INDEX_D
> ['1','1111'] - ['5','3333']
> 6. but query data on 'F'
> explain select * from INDEX_TEST_TABLE where A in ('1','2','3','4','5') and F
> in ('1111','2222','3333');
> 7. also use the index on 'D' and set filter on 'F'
> CLIENT PARALLEL 1-WAY SKIP SCAN ON 5 KEYS OVER INDEX_TEST_TABLE_INDEX_D ['1']
> - ['5'] |
> SERVER FILTER BY F IN ('1111','2222','3333') |
> is this a bug in 4.1 version??
