Perplexity Search Operator and Advanced Query Rules

Master Perplexity search with these advanced operator rules:

1. SITE FILTERING: Use "site:example.com" to restrict results to specific domains. Example: "site:arxiv.org transformer attention mechanisms 2024"

2. FILETYPE FILTERING: Use "filetype:pdf" to find specific document types. Example: "filetype:pdf market research report AI healthcare 2024"

3. RECENCY INSTRUCTIONS: Add explicit time constraints to your queries: "Using sources from the last 30 days, summarize..." or "Find information published after January 2024 about..."

4. EXCLUSION: Use negative keywords to filter noise: "AI regulation NOT chatbot NOT consumer" focuses on enterprise/government AI regulation.

5. COMPARISON QUERIES: Structure comparisons explicitly: "Compare X vs Y on: price, performance, scalability, community size. Format as a table."

6. FOCUS MODES: Writing mode for creative/technical writing. Math mode (Wolfram Alpha) for calculations and data analysis. Standard mode for general research. Choose the appropriate mode before querying.

7. THREAD STRATEGY: Use Perplexity Threads for iterative research. Start broad ("Overview of quantum computing market"), then narrow ("Top 3 quantum computing startups by funding in 2024"), then force precision ("What is IonQ's annual revenue for fiscal year 2024?").

8. SOURCE QUALITY: Add "Cite every claim with a URL, or respond with 'I don't know'" as a fail-fast clause to prevent hallucination.
