   Maybe we can create two `Vec<expr>` lists on the TableScan like 
`exact_filters` and `inexact_filters` to make the filtering expectations very 
clear
   
   That would lead to an explain like:
   
   ```
   
--------------------------------------------------------------------------------------------+
   | plan_type     | plan                                                       
                                                                                
                                                        |
   
+---------------+----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+
   | logical_plan  | Projection: #test.request                                  
                                                                                
                                                        |
   |               |   Filter: #test.request = Utf8("foo")                      
                                                                                
                                                        |
   |               |     TableScan: ... inexact_filters=[#test.request = 
Utf8("foo")]  exact_filters=[#test.request = Utf8("bar")]                       
                                           
   ```
   
   Maybe terms like `partial_filters` and `full_filters` would be better? 🤔
