New Feature: Parallel Multi-Engine Search

The Problem with Single-Engine Search

Every search engine has its own index. Google might surface results that Bing doesn't know about, and DuckDuckGo may find pages that Yahoo misses. When you search one engine at a time, you're only seeing a fraction of what's out there.

Previously, extracting from multiple engines meant running separate searches sequentially — first DuckDuckGo, then Bing, then the next one. This worked, but it was slow.

How Parallel Search Works

With parallel multi-engine search, EmailExtractorMax sends your query to all selected engines at once. Each engine processes your request independently, and results stream in as they're found from every source simultaneously.

Here's what happens when you click "Start" with multiple engines enabled:

1. Your search query is sent to all selected engines in parallel
2. Each engine returns its own set of search result URLs
3. The app begins visiting result pages from all engines concurrently
4. Emails are extracted and deduplicated in real-time
5. Results appear in the table as they're found — no waiting for any single engine to finish

Supported Engines

EmailExtractorMax currently supports five search engines:

• Google — The largest search index, with 30+ country-specific variants
• DuckDuckGo — Privacy-focused search with unique results
• Bing — Microsoft's engine with strong coverage of business websites
• Brave — Independent search engine with its own crawled index
• Yahoo — Wide coverage with results that often differ from other engines

Why Different Engines Return Different Results

Search engines differ in how they crawl, index, and rank pages. A page that ranks highly on Google might not even appear in Bing's top 100. Some engines prioritize newer content, others favor established domains. By searching all of them, you cast the widest possible net.

In our testing, using all five engines together typically yields 40-60% more unique emails compared to using any single engine alone.

Smart Rate Limiting

Sending too many requests too quickly can trigger rate limiting from search engines. EmailExtractorMax handles this automatically with built-in delays and user-agent rotation for each engine. The parallel search is designed to be fast but respectful — maximizing results without getting blocked.

How to Use It

1. Open EmailExtractorMax and switch to the Search Engines tab
2. Enter your search query
3. Check the boxes for the engines you want to use (we recommend all five)
4. Click "Start" and watch results pour in from multiple sources

That's it. No configuration needed — parallel search just works.
