-----------------------------
Description:
repro steps：
build 2 segs in a cube, [2012-01-01 - 2012-01-03] And [2012-01-03 - 2012-01-05]
query: select sum(PRICE) from KYLIN_SALES
where "KYLIN_SALES"."PART_DT" = DATE '2012-01-01'
OR "KYLIN_SALES"."PART_DT" = DATE '2020-07-02'
Expected results：segment[2012-01-03 - 2012-01-05] should not be scaned, should be pruned by SegmentPruner
but i found in method 'org.apache.kylin.cube.common.SegmentPruner#satisfy'
when filter's operator is "In", when satisfy segment[2012-01-03 - 2012-01-05] ,the function return true
