   @Jackie-Jiang `BETWEEN` returns more segments than `=` does (it picks up 3 
segments where `=` picked up 2).
   
   If I query for a known $docId like:
   ```
   select $segmentName, DATETRUNC('day', "blockTimestamp") 
"blockTimestamp_day", $docId from "0c98d17f-fb19-42fa-bca3-54b9f1750e0f_OFFLINE"
   where blockTimestamp_day = fromDateTime('2021-05-11', 'yyyy-MM-dd') and 
$segmentName = 
'0c98d17f-fb19-42fa-bca3-54b9f1750e0f_OFFLINE_1620669780000_1620707462000_1469_87cec857-1140-4a46-b722-53d869aa871d'
 and $docId = '16'
   ```
   
   I get no results, even though that docId showed up in the `between` version 
of the query.
   
   Here's the plan for the between:
   ```
   
   
   BROKER_REDUCE(limit:10) | 1 | 0
   -- | -- | --
   COMBINE_GROUP_BY | 2 | 1
   PLAN_START(numSegmentsForThisPlan:2) | -1 | -1
   GROUP_BY(groupKeys:$segmentName, $blockTimestamp$DAY, aggregations:count(*)) 
| 3 | 2
   PROJECT($segmentName, $blockTimestamp$DAY) | 4 | 3
   DOC_ID_SET | 5 | 4
   
FILTER_RANGE_INDEX(indexLookUp:range_index,operator:RANGE,predicate:$blockTimestamp$DAY
 BETWEEN '1620691200000' AND '1620691200000') | 6
   ```
