How it's used
Often carries a slightly negative or critical nuance, implying that someone is being overly pedantic or prying into things that are better left alone. It is frequently used in contexts where someone is questioning motives or details that do not really matter. While it can mean to study something in depth, it is more commonly used in daily life to describe digging for information or holding someone accountable for past actions.
Examples
Why do you have to dig into other people's privacy?

Common mistake
Do not confuse this with 鑽牛角尖, which refers to being stuck in a narrow way of thinking or obsessing over minor details. 深究 is about the act of investigating or questioning, whereas 鑽牛角尖 describes the mental state of being unable to let go of a trivial point.
