為無
"為無" is not a standard phrase in Chinese. It might involve a typo or require additional context for accurate interpretation.
This usage of '為無' involves the prefix '為' meaning 'about' or 'for', and '無' indicating 'not having'—together they describe focusing on matters without meaning.
他總是為無意義的問題煩惱。

We shouldn't feel ashamed for being ignorant.
This sentence uses '為' to mean 'as result of', and '無所獲' interprets as 'achieved nothing'—describing the outcome of actions.
