Q: What are the three main characteristics of a search engine?
A: 1.) Crawl - The search for web content. Early search programs started off finding only documents and URLs, more specifically as educational articles/journals. Crawl has expanded to find video, audio, images, shopping content, etc.
2.) Index - The list of locations of the content found by the crawler. The larger the index, the better the search engine. The goal of all search engines is to index the entire WWW.
3.) The Runtime/Query System - the interface and related software that connects a user’s queries to the index, also manages relevance and importance. The box where queries are entered, and the results page that follows.
