+
+```python
+import requests
+
+def web_search(query):
+    """Recherche web via SearXNG auto-hébergé"""
+    searxng_url = "http://192.168.1.27:11112"
+    
+    try:
+        response = requests.get(
+            f"{searxng_url}/search",
+            params={
+                "q": query,
+                "format": "json",
+                "engines": "google,bing,duckduckgo,qwant",
+                "language": "fr"
+            },
+            timeout=15
+        )
+        
+        if response.status_code == 200:
+            results = response.json()
+            formatted = []
+            
+            for r in results.get("results", [])[:10]:
+                title = r.get("title", "Sans titre")
+                url = r.get("url", "")
+                snippet = r.get("content", "")[:200]
+                formatted.append(f"**{title}**\n{snippet}\n🔗 {url}")
+            
+            if formatted:
+                return "## Résultats\n\n" + "\n\n".join(formatted)
+            
+            return "Aucun résultat."
+        
+        return f"Erreur {response.status_code}"
+    
+    except Exception as e:
+        return f"Erreur: {str(e)}"
+```
