Perplexity Hybrid Search and the Sonar Engine
A retrieval architecture combining literal keyword matching with dense semantic vector search, then verifying across sources and synthesising with citations attached to individual claims.
Analogy Mental model
One team of librarians searching by exact title, another by what the book is about, and an editor combining whatever both agree on into a summary with a footnote on every line.
In practice What you actually do
The interface offers focused modes for the open web, academic papers, writing, video, and community discussion. For considered purchases, users switch into the community and video modes specifically to verify real-world experience, so coverage across web, forum, and video is required rather than optional.
Where people get burned Pitfalls
Its fetcher is impatient. A page that has not delivered readable HTML within a couple of seconds, because of blocking scripts or slow server response, is abandoned and the next source is tried instead.
