## 🚀 Beyond the Basics: Advanced Agentic Patterns
|
||||
|
||||
### The Power of Agentic Research Pipelines
|
||||
|
||||
What you've built is just the beginning! The beauty of Crawl4AI's URL Seeder is that it enables sophisticated agentic workflows. Let's explore an advanced pattern with reflection and iterative discovery:
|
||||
|
||||
### Advanced Pattern: Multi-Query Reflection Loop
|
||||
|
||||
Instead of a linear pipeline, imagine an intelligent agent that:
|
||||
1. Generates multiple search strategies from your query
|
||||
2. Discovers URLs from different angles
|
||||
3. Evaluates if it has enough information
|
||||
4. Iteratively searches for missing pieces
|
||||
5. Only stops when confident in its findings
|
||||
|
||||
Here's how this advanced flow works:

||||
