Yeah, the AND vs OR distinction makes sense, and I think it fits well into the larger conceptual framework I have in mind.
So maybe there are two categories of keyword search:
1. feeds
- results arranged in reverse chronological order
- search criteria combined via OR
- examples from the fiat world: Twitter, fb, other social media
2. Non-feed search results
- results arranged by “importance scores”
- search criteria combined via AND
- examples from the fiat world: Google search
The first case, you’re basically engaged in conversations with other users, so a strong recency bias makes sense. In the second case, you’re looking for info that is not necessarily recent. There is no “conversation” per se.
What do you think?
