If a user unsubscribes from a feed, what is the outcome regarding message searches?

When a user unsubscribes from a feed, they effectively remove their active participation and engagement with that feed. This action includes not just stopping notifications about new messages but also restricting their ability to search through previous messages posted within that feed. Unsubscribing is intended to disengage the user from all aspects of that feed, including its message history.

Consequently, the outcome of unsubscribing is that the user will not be able to search for messages from that feed anymore. Thus, all interactions and retrieval of content relating to that feed are effectively cut off for the user. This is critical in ensuring that users maintain control over the content they wish to engage with, keeping their experience tailored to their preferences.
