## Advanced Configuration

### Multi-Instance Crawling

```java
// Create multiple crawler instances
Crawler crawler1 = container.getComponent("crawler");
crawler1.setSessionId("session1");
crawler1.addUrl("https://site1.com");

Crawler crawler2 = container.getComponent("crawler");

Lorsque vous importez `Query`, `Path` et d'autres de `fastapi`, ce sont en fait des fonctions.

Ces dernières, lorsqu'elles sont appelées, renvoient des instances de classes du même nom.

Ainsi, vous importez `Query`, qui est une fonction. Et lorsque vous l'appelez, elle renvoie une instance d'une classe également nommée `Query`.
