LES MOTEURS DE RECHERCHE

Moteur de recherche, c’est quoi ?

Un moteur de recherche est un logiciel permettant de retrouver des ressources (pages web, forums, musiques, images, vidéo, etc.) associées à des mots quelconques. Des robots (logiciels), appelés spiders (en français araignées) doivent parcourir la toile en suivant récursivement les liens des millions de pages Web et indexent le contenu dans de gigantesques bases de données afin de permettre leur interrogation.
Aucun moteur de recherche ne peut parcourir la totalité des pages en une journée (ce processus prend généralement plusieurs semaines), chaque moteur adopte donc sa propre stratégie, certains allant même jusqu’à calculer la fréquence de mise à jour des sites.

Lorsque l’utilisateur d’un moteur de recherche remplit le formulaire, il spécifie les mots qu’il cherche (éventuellement ceux qu’il ne souhaite pas). La requête est envoyée au moteur de recherche qui consulte ses bases de données pour chacun des mots puis affine la recherche en enlevant les pages ne convenant pas.
Il retourne ensuite une liste de liens vers des pages, avec soit le début du texte de la page, soit le texte spécifié par le créateur de la page grâce aux balises spécifiques, appelées méta-tags, ou encore l’extrait de la page qui contient les mots recherchés.
Ces réponses sont classées dans un ordre de pertinence, correspondant à des critères propres au moteur de recherche, tels que le pourcentage de mots correspondant à la recherche, leur indice de densité (le nombre d’occurence de chacun des mots clés dans la page), etc.

Les differents moteurs de recherche

Google : Simple et efficace, il est probablement l’un des puissants, et est devenu une référence sur la recherche sur Internet.
Le moteur de recherche Google, qui a donné le nom à la société Google, est le moteur de recherche sur Internet le plus utilisé au monde.

 

Voilà : Voila.fr est un moteur très puissant. Mais ce site propose aussi de nombreux services tels que des adresse E-Mail, Chat, Actualités, Horoscope…Il est fondé sur un moteur de recherche francophone.


Lycos : Comme Voila, Lycos fournit un moteur de recherche puissant, associé à un Annuaire. Cet annuaire regroupe par catégories des sites web que Lycos a vérifié manuellement et auxquels il a attribué une note.


Altavista :Cet excellent moteur de recherche brille par sa rapidité et ses nombreuses innovations. Son spider Scooter est lui aussi rapide et n’aime pas spécialement le spam…
