andygrove opened a new issue, #2133:
URL: https://github.com/apache/datafusion-comet/issues/2133
### Describe the bug
In `QueryPlanSerde`, there is specific handling of some string expressions
for `FilterExec`.
```scala
// Some native expressions do not support operating on
dictionary-encoded arrays, so
// wrap the child in a CopyExec to unpack dictionaries first.
def wrapChildInCopyExec(condition: Expression): Boolean = {
condition.exists(expr => {
expr.isInstanceOf[StartsWith] || expr.isInstanceOf[EndsWith]
|| expr
.isInstanceOf[Contains]
})
}
```
However, it is possible for these expressions to exist in other operators,
such as `ProjectExec`, and it does not look like we add `CopyExec` in those
cases.
