Abstract
Das Internet mit seinen ständig neuen Usern und seinem extremen Wachstum bringt viele neue Herausforderungen mit sich. Aufgrund dieses Wachstums bedienen sich die meisten Leute der Hilfe von Suchmaschinen um Inhalte innerhalb des Internet zu finden. Suchmaschinen nutzen für die Beantwortung der User-Anfragen Information Retrieval Techniken. Problematisch ist nur, dass traditionelle Information Retrieval (IR) Systeme für eine relativ kleine und zusammenhängende Sammlung von Dokumenten entwickelt wurden. Das Internet hingegen unterliegt einem ständigen Wachstum, schnellen Änderungsraten und es ist über geographisch verteilte Computer verteilt. Aufgrund dieser Tatsachen müssen die alten Techniken erweitert oder sogar neue IRTechniken entwickelt werden. Eine Suchmaschine die diesen Herausforderungen vergleichsweise erfolgreich entgegnet ist Google. Ziel dieser Arbeit ist es aufzuzeigen, wie Suchmaschinen funktionieren. Der Fokus liegt dabei auf der Suchmaschine Google. Kapitel 2 wird sich zuerst mit dem Aufbau von Suchmaschinen im Allgemeinen beschäftigen, wodurch ein grundlegendes Verständnis für die einzelnen Komponenten geschaffen werden soll. Im zweiten Teil des Kapitels wird darauf aufbauend ein Überblick über die Architektur von Google gegeben. Kapitel 3 und 4 dienen dazu, näher auf die beiden Komponenten Crawler und Indexer einzugehen, bei denen es sich um zentrale Elemente im Rahmen von Suchmaschinen handelt.
