Search Engines are the Data Machines. They have software, called robots / spiders. Robots are following the links on the internet, crawling & indexing. And spew it out when someone is searching for that specific data.
hi search engine are the websites which helps you to find the conetent which is present over the internet, Google is on top of the search engine followed by the yahoo and bing.
the basic them of search engine is that there is different algorithms which helps you for the specific search
Via Search Engine we can search any of the queries creeping in our mind. Search engine first matches the title followed by the heading tag and then description. Refer to: iquantum.com.au Thanks Online Marketing
Search Engines are the data centers having answers to all your search quires. They send their spiders to fetch the accurate data you require while searching for some thing on the cyber space.
A program that searches a document for a specific keyword and return a list of a document where the keyword were found.When people use the term search engine in relation to the web they are usually referring to the actual search term that searches through database of html document, initially gather by a robot.

By definition, an Internet search engine is an information retrieval system, which helps us find information on the World Wide Web. World wide web is the universe of information where this information is accessible on the network. It facilitates global sharing of information. But WWW is seen as an unstructured database. It is exponentially growing to become enormous store of information. Searching for information on the web is hence a difficult task. There is a need to have a tool to manage, filter and retrieve this oceanic information. A search engine serves this purpose. How Does Work: Internet search engines are web search engines that search and retrieve information on the web. Most of them use crawler indexer architecture. They depend on their crawler modules. Crawlers also referred to as spiders are small programs that browse the web. Crawlers are given an initial set of URLs whose pages they retrieve. They extract the URLs that appear on the crawled pages and give this information to the crawler control module. The crawler module decides which pages to visit next and gives their URLs back to the crawlers. The topics covered by different search engines vary according to the algorithms they use. Some search engines are programmed to search sites on a particular topic while the crawlers in others may be visiting as many sites as possible. The crawl control module may use the link graph of a previous crawl or may use usage patterns to help in its crawling strategy. The indexer module extracts the words form each page it visits and records its URLs. It results into a large lookup table that gives a list of URLs pointing to pages where each word occurs. The table lists those pages, which were covered in the crawling process. A collection analysis module is another important part of the search engine architecture. It creates a utility index. A utility index may provide access to pages of a given length or pages containing a certain number of pictures on them. During the process of crawling and indexing, a search engine stores the pages it retrieves. They are temporarily stored in a page repository. Search engines maintain a cache of pages they visit so that retrieval of already visited pages expedites. The query module of a search engine receives search requests form users in the form of keywords. The ranking module sorts the results. The crawler indexer architecture has many variants. It is modified in the distributed architecture of a search engine. These search engine architectures consist of gatherers and brokers. Gatherers collect indexing information from web servers while the brokers give the indexing mechanism and the query interface. Brokers update indices on the basis of information received from gatherers and other brokers. They can filter information. Many search engines of today use this type of architecture.
you can search anything that give you answer related to search that's call search engine some example google, yahoo, msn(bing) etc. all search engine work base on algorithm.
hi, Google is a search engine. the google Internet search engines are web search engines that search and retrieve information on the web. Most of them use crawler indexer architecture. They depend on their crawler modules. Crawlers also referred to as spiders are small programs that browse the web.
A web search engine is designed to search for information on the World Wide Web and FTP servers. The search results are generally presented in a list of results often referred to as SERPS, or "search engine results pages". The information may consist of web pages, images, information and other types of files. Some search engines also mine data available in databases or open directories. Unlike web directories, which are maintained only by human editors, search engines also maintain real-time information by running an algorithm on a web crawler.
Search engines help you in searching any kind of information/data over internet. One of the most popular search engines is Google.
search engine is a website that helps you finding the solution of your problems that your facing or if you need to find detail about anything that you can find in it
Search engines like google work through storing details about numerous website pages, which they get from your html code alone. These webpages are retrieved by way of a Internet crawler - an automatic Browser which follows each and every website link on the website.The particular contents of each and every web page are usually then examined to determine the actual way it should be indexed.
A search engine is simply an index of various sites depending on keywords and ranking, and searching their database, will promot the search engines to display their results according to how they determine their relevance
