Connect and share knowledge within a single location that is structured and easy to search. However, the || operator actually returns the value of one of the specified operands, so if this operator is used with non-Boolean values, it will return a non-Boolean value. Longer term: I don't think it is easy to fix the searchsorted directly, as here it is a numpy call, where the passed integer array gets converted to an object numpy array (at least if we don't want to change the coercing behaviour of IntegerArray and the comparison and boolean behaviour of pd.NA). I'd expect the output for the pd.NA operations above to match the output of the equivalent np.nan operations. If you want to cover whole elements, use axis=None. Access a zero-trace private mode. In most cases, note the following two points. Probably need to report the bug to numpy? Error builtins.TypeError: boolean value of NA is ambiguous is raised where there is a missing value in a boolean expression.
