Semantic Search
Semantic search matches queries to content by meaning rather than exact words. Searching 'negotiating a raise' can surface a post titled 'how I got my salary bumped 20%' — no shared keywords required.
How it differs from keyword search
Full-text (keyword) search requires you to guess words that literally appear in the document. Semantic search converts both query and content into representations of meaning (embeddings) and matches those, so synonyms, paraphrases, and descriptions all connect to the right result.
Where it shines
Personal archives are the ideal use case, because you remember the gist of what you saved, not the phrasing. That's why searching your own Reddit saves benefits more from semantic search than searching the open web — you already know the answer exists; you just can't name it.
