Search Technology

Search technology refers to the various techniques available to search engines to provide the right information users are searching for. All search engines and other search tools on the Internet depend on search technology for their functioning.

Search engines use robots termed spiders and web crawlers for a variety of purposes. The robot or spider is a software program that can navigate the hypertext in a document. The robots index the web pages which are later on referred to by the search engines. Robots use different strategies to index web pages. They give primary preference to documents like server lists, pages listing new developments and other popular websites with a number of links to other sites.

When you pose a query to a search engine, mainly by giving keywords, the search engine refers to the index made and comes up with a list of matching results. Leading search engines are endowed with the ability to rank results according to their relevance. This method of ranking varies from one search engine to another. To receive the attention of search engines, web content developers have to provide search engine optimized web content in their websites. Search engine optimized web content is characterized by the right keyword density, key phrases, appropriate use of title tags, Meta tags, and page text.

Keyword and key phrase based search is the most popular method of searching. However, at present research is progressing in various directions to augment the already existing search technology. The areas in which researchers are concentrating include vertical engines, search based on meaning and content, improved indexing and so on.

With advancement in computer research, search technology is being updated on a regular basis. Web pages will now have to be optimized in accordance with the respective search technology in order to secure the maximum number of visitors. Software developers are trying to improve the existing browsers to provide users a better search experience on the Internet. Search technology is now being advanced to provide search results in clusters or groups which facilitate refining and expanding your search.
