```
    tests if current expression involves an indexed funciton AND that function can also be executed without using the index
    
    Parameters:
    
    target - the query target
    
    context - the execution context
    
    Returns:
    
    true if current expression involves an indexed function AND that function can be used on this target, false otherwise

```
    tests if current expression involves an indexed function AND that function can be used on this target
    
    Parameters:
    
    target - the query target
    
    context - the execution context
    
    Returns:
    
    true if current expression involves an indexed function AND that function can be used on this target, false otherwise
  - executeIndexedFunctionAfterIndexSearch

public boolean executeIndexedFunctionAfterIndexSearch(OFromClause target,
                                                      OCommandContext context)
```
    tests if current expression involves an indexed function AND the function has also to be executed after the index search. In some cases, the index search is accurate, so this condition can be excluded from further evaluation. In other cases the result from the index is a superset of the expected result, so the function has to be executed anyway for further filtering
    
    Parameters:
    
    target - the query target
    
    context - the execution context
    
    Returns:
    
    true if current expression involves an indexed function AND the function has also to be executed after the index search.
