In hadiths, how do you know when "knowledge" means religious knowledge or any knowledge?

In some hadiths it's clear knowledge of religion is being discussed, some are clear that any knowledge is being discussed, but what about rest. Do all hadiths have context that you can read somewhere. Is there an established approach? I've come across insincere approaches from two sides, where one side claim every mention of knowledge is only referring to religious knowledge, whereas other side does the opposite. Yet in some case neither have any good justification for their claim. And in most one side is correct based on reasonable conclusion derived from context.
