Reddit Discussion Thread Retrieval And Ranking

via “threaded discussion aggregation and ranking”

</details>

Unique: Implements a simple but effective time-weighted ranking system that combines vote count with submission recency using a decay function, rather than pure chronological or pure popularity sorting. The tree-based comment structure with collapsible threads allows users to navigate deep discussion hierarchies without losing context of parent comments.

vs others: Simpler and faster than algorithmic feeds (Reddit, Twitter) because it uses deterministic scoring rather than ML-based ranking, making it more predictable for power users while sacrificing personalization

Unique: Treats Reddit discussions as a first-class review source with dedicated ranking and deduplication logic, rather than treating Reddit as supplementary external links. Indexes discussion context and alternative recommendations, not just product mentions.

vs others: Surfaces authentic peer conversations that Google Shopping and Amazon suppress, whereas Reddit's native search is poor for product discovery and requires manual subreddit navigation
