Search Engine

a program that searches for and identifies items in a database that correspond to keywords or characters specified by the user, used especially for finding particular sites on the World Wide Web.

How Do Create Search Engine Like Google?

A search engine fundamentally needs to accept some sort of search query (for instance, a series of words) and then return web resources that it thinks are appropriate to the query. The way it decides what is appropriate to the query can be very important. One can use a simple algorithm like counting how many times any of the search words appears on a page. Google uses sophisticated techniques, including investigating the pages that link to a given page.


Google itself gives some tools to embed their technology in each own's projects:

  • Google Custom Search, searchs only a specific portion of the web, with custom rules
  • Google AJAX Search lets you put a customized search form in you pages
  • Google Enterprise and Google Search Appliance are scalable solutions that use Google's technology to search private intranets or index company's documents
