Focus & Pro Search: pick the right mode
Goal. Steer where Perplexity looks (the whole web vs. academic sources) and how hard it works (a quick answer vs. a multi-step Pro Search), so the answer's sources match the job.
What does recent literature say about the link between sleep deprivation and amyloid-beta clearance?
Run this twice: once on the default web search, once with the source set to Academic. Compare the citation lists — Academic should pull peer-reviewed papers (e.g. PubMed, arXiv, Google Scholar) instead of news sites and blogs.
- 1Set the search source. Near the search bar there's a control to choose where Perplexity looks — the default searches the whole web; Academic restricts it to scholarly literature. Other scopes (e.g. Social, Finance) exist for non-research questions.
- 2Use Academic for anything you'd cite. It surfaces peer-reviewed papers rather than SEO content — the difference between a citable source and a blog summarising it.
- 3Turn on Pro Search for harder questions. Pro Search breaks your question into sub-steps and pulls from a wider set of sources, so it's better for multi-part or comparison questions than a single quick lookup.
- 4Trick: match the mode to the stakes. A quick fact → default web. A claim you'll put in a paper or a grant → Academic + Pro Search, every time.
You'll see. The same question answered two ways: a default web answer citing mixed sources, and an Academic answer citing journals and preprint servers — visibly more trustworthy for research.
Cost. Academic source selection is free. Pro Search is rate-limited on the free tier (a handful of uses, then a cooldown before it resets); Pro removes that limit.
Takeaway. Two dials: where it looks (Academic for citable sources) and how hard it works (Pro Search for multi-step questions). Set both to match what the answer is for.
