How Discover works

Discover uses news search to find current, relevant articles:

​
Content fetching

For each topic, Discover searches across multiple trusted sources: 
const topicConfig = {
  query: ['technology news', 'latest tech', 'AI', 'science and innovation'],
  links: ['techcrunch.com', 'wired.com', 'theverge.com']
}
Search process:
  1. Combines each query term with each source domain
  2. Searches using Bing News engine via SearxNG
  3. Aggregates results from all combinations
  4. Removes duplicate URLs
  5. Randomizes order for variety
Discover uses the Bing News engine through SearxNG to find recent, newsworthy articles from trusted sources.

​
Normal vs. Preview mode

Discover supports two fetching modes: Normal mode:
  • Fetches from all sources and queries
  • Comprehensive coverage of the topic
  • More results for browsing
  • Takes slightly longer to load
Preview mode:
  • Selects one random source and query
  • Faster loading
  • Smaller sample of content
  • Good for quick previews
GET /api/discover?topic=tech&mode=normal
GET /api/discover?topic=finance&mode=preview

​
Privacy and content curation

Discover is designed with privacy in mind:
  • No tracking of what you read
  • No personalization based on browsing history
  • No user profiling or data collection
  • Content sources are predefined, not algorithm-driven
  • Fresh results on each visit
Unlike personalized news feeds, Discover shows the same trending content to everyone. This avoids filter bubbles and exposes you to diverse perspectives.

​
Using Discover

To use the Discover feature:
  1. Navigate to the Discover section in Perplexica
  2. Select a topic that interests you
  3. Browse the articles displayed
  4. Click any article to read the full content at the source

Benefits:

​
Content freshness

Discover content is fetched in real-time:
  • No caching of article lists
  • Each visit fetches current results
  • Trending and recent content prioritized
  • Sources update continuously
Refresh the Discover feed to see new articles. Since content is fetched in real-time and randomized, each load may show different articles.

​

The Discover API returns a list of articles: 
{
  blogs: [
    {
      url: string;
      title: string;
      content: string;
      publishedDate?: string;
      // Additional metadata from search results
    }
  ]
}

​

  • Freshness: Regular publication of new content
  • Reliability: Consistent quality and fact-checking
