@cccs-jc Thanks for your proposal!
For filter `col1=1 || col2=1`, the current implementation is:
```
shouldRead = statsFilter(col1=1 || col2=1) && dictFilter(col1=1 || col2=1)
&& bloomFilter(col1=1 || col2=1)
```
Your suggested modification appears to be:
```
shouldRead = (statsFilter(col1) && dictFilter(col1=1) &&
bloomFilter(col1=1))
|| (statsFilter(col2) && dictFilter(col1=2) && bloomFilter(col1=2))
```
This approach seems logically sound. However, the change you proposed may
require modifications to the current predicate evaluation model. I suspect this
could necessitate quite a few adjustments.
