richtia opened a new issue, #10861:
URL: https://github.com/apache/datafusion/issues/10861
### Is your feature request related to a problem or challenge?
Datafusion doesn't not have a contains function and will return an exception
if a substrait plan contains it
```
Exception: DataFusion error: NotImplemented("Unsupported function name:
\"contains:str_str\"")
```
### Describe the solution you'd like
When the datafusion consumer sees the `contains` function, it can convert it
to a combination of `strpos` + `>`
```
strpos(lit("abcd"), lit("de") > 0
```
### Describe alternatives you've considered
