How Do Search Engines Work
{"Image DocumentName": "How Do Search Engines Work?", "Image ImageDescription": "Spider crawls the web to find new documents (web pages, other documents) typically by following hyperlinks from websites already in their database. Search engines indexes the content (text, code) in these documents by adding it to their databases and then periodically updates this content. Search engines search their own databases when a user enters in a search to find related documents (not searching web pages in real-time) Search engines rank the resulting documents using an algorithm (mathematical formula) by assigning various weights and ranking factors. If you were not take anything away from this session today\u2026 and only understand how Spider or crawlers work you would have understood 40% of Search engines.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
