will show you some of the main concepts you should probably keep in mind when deploying a **FastAPI** application (although most of it applies to any other type of web application).

You will see more details to keep in mind and some of the techniques to do it in the next sections. ✨...

     * <p>
     * This method checks if the resolved absolute path starts with the allowed base directory,
     * preventing access to files outside the intended directory through path traversal
     * techniques like "../../../etc/passwd".
     * </p>
     * <p>
     * Example usage:
     * </p>
     * <pre>
     * Path baseDir = Paths.get("/var/app/data");
     * Path userPath = Paths.get(userInput);

But it is way more complex than that.

// Clauses Add clauses
//
// This supports both standard clauses (clause.OrderBy, clause.Limit, clause.Where) and more
// advanced techniques like specifying lock strength and optimizer hints. See the
// [docs] for more depth.
//
//	// add a simple limit clause
//	db.Clauses(clause.Limit{Limit: 1}).Find(&User{})

`FastAPI` est une classe qui hérite directement de `Starlette`.

Vous pouvez donc aussi utiliser toutes les fonctionnalités de [Starlette](https://www.starlette.dev/) avec `FastAPI`.

 * The processor maintains a pool of searchers and an executor service for concurrent operations.
 * It implements rank fusion techniques to combine results from different search engines
 * and provides a unified search interface.
