Search the Web
No two search engines are identical, and this is partly due to the way that each search engine's spider operates. While some spiders gather information by following home page links to internal and external web pages, others look only for the most popular web pages. Still others, like ASearch.us, gather information about, and highlight, a predefined list of web sites. Some search engine spiders are configured to ignore files that contain graphics, animation, or sound.
As the spider gathers information, the search engine's software gathers Universal Resource Locators (URLs) and documents, and sends them to the indexing software. The manner in which the information is extracted and indexed varies from search engine to search engine. Some search engines index every word in a document, while others index only the key words.
When you type in a certain keyword or phrase, relevant documents and URLs will appear after the database is searched. When you click on the link to a document or URL, you are taken directly to the document. Thanks to search engines, web surfers can find the information they are looking for quickly and accurately!
