- Wolfram Alpha Search Mode: Provides solutions for queries requiring calculations or data analysis via Wolfram Alpha.
- Reddit Search Mode: Searches Reddit for discussions and opinions that are pertinent to your query.
Current Information Assurance:
Unlike other search tools that might provide outdated information from crawling bots converted into embeddings stored in an index, Perplexica leverages SearxNG. This metasearch engine not only fetches results but also re-ranks them to ensure you always receive the most current and relevant information without the burden of daily data updates.
Perplexica’s integration of SearxNG ensures that the information delivered is always up-to-date while prioritizing user privacy. By meticulously scoring sources, SearxNG maintains a high standard of quality in the search results. Moreover, Perplexica goes the extra mile by providing clear answers accompanied by cited sources, promoting transparency and building trust with its users.

Curious about how Perplexica works?
To understand how Perplexica operates, consider this scenario: A user asks, “How does an A.C. work?“. Here’s a breakdown of Perplexica’s process using the “webSearch” focus mode:
- Message Transmission: The user’s question is sent via WebSocket (WS) to the backend server, triggering the operational chain tailored to the selected focus mode.
- Chain Activation: Initially, the system evaluates the need for external sources based on the chat history and the question itself. If necessary, a web search query is formulated. If no external information is needed, this stage concludes, and the response generation phase begins.
- Web Search: The formulated query is executed using SearXNG, a search engine, to gather relevant information from the web.
- Information Processing: The retrieved data is transformed into embeddings, similar to the query embeddings. A similarity search then identifies the most pertinent sources.
- Response Generation: Integrating the chat history, query, and identified sources, the response generator crafts a reply. This response is then streamed to the user interface (UI), completing the process.
This streamlined explanation covers each critical stage of Perplexica’s functionality, providing a clear view of its operational dynamics. To learn more jump over to the official GitHub repository where more documentation is available
