EDIT: Je sais qu'il est AJAX envoyé avec chaque pression de touche, mais est-ce prédictif? Ou pensez-vous qu'il est juste un ol régulier » google recherche?

• À propos de Google Instant

Answer 2

Comme d'autres l'ont dit, Google est instantanément de retour des résultats pour le résultat de plus de ce que Google Suggest suggère . Par conséquent, si vous tapez fac , Google suggère que vous entrez en facebook . Fait intéressant, seul le terme de recherche partielle, fac , est envoyé à Google dans la demande JSON, afin que Google Suggest est utilisé aux deux extrémités.

recherches ne sont pas réellement effectuées sur tous combinaison de touches. Si vous tapez assez vite, certains peuvent obtenir manquer.

Je pense que cela n'augmente pas la charge sur les serveurs de Google, autant que vous pourriez penser. La plupart des recherches supplémentaires sont des mots très populaires quand vous commencez à des choses de frappe - si vous commencer à chercher quelque chose en commençant par f , il recherche facebook , si vous commencez la recherche de début de quelque chose avec ju , il recherche justin bieber . Merci à la mise en cache, ces recherches ne sont pas très coûteux de le faire.

Answer 3

Il est prédictif. Les résultats de recherche sont de la première suggestion de saisie semi-automatique (ou celle sélectionnée si vous appuyez sur la flèche vers le bas ou la souris sur une suggestion).

En d'autres termes, si je tape « vinyle s », la première suggestion de saisie semi-automatique est « bardage en vinyle, » et les résultats de la recherche montrent clairement une recherche de « bardage en vinyle. » Si je fais une recherche google normale pour « vinyle s, » les résultats de la recherche sont différents.

Google Instant est un facteur prédictif d'une manière que les recherches google normales ne sont pas ... il recherche la saisie semi-automatique suggéré au lieu de la requête de recherche inachevée littérale.

Answer 4

Conversion de la première valeur de u clé dans la réponse Ajax réponse de Daniel Vassallo donne un Version décompressé . Il est la plupart du temps une balise de script, qui passe 2 plus morceaux de HTML à une je.pa() fonction. Ces morceaux semblent être les mêmes que les résultats de la recherche non instantanée.

Answer 5

Il y a quelque temps j'ai écrit une interface graphique de recherche instantanée vaguement populaire pour le moteur de recherche Solr. Son très simple, vous devriez donc être en mesure de regarder le code et comprendre les concepts généraux http: //fergiemcdowall.github .io / solrstrap /
