WEB OR EMAIL BASED SEARCH ENGINE

Platform : JAVA

WEB OR EMAIL BASED SEARCH ENGINE A Search Engine helps you find things on the Internet. Any time anyone looks up anything on the Internet, where they start from scratch, they're probably using a search engine. There are individual Search Engines, Some Search Engines don't even do their own listings, and they just search those of other Search Engines. Another way to define Search Engines is special web sites designed to serve as searchable "indices" for the Search engines typically employ computer programs that continually collect information about web pages and organize this information in a searchable database. (These programs are sometimes called "spiders"--they traverse all (or at least many) of the branches of the web that connects web pages, following from link to link, much as a spider could walk the strands of its web.) The term "search engine" is often used generically to describe both crawler-based search engines and human-powered directories. These two types of search engines gather their listings in radically different ways. Crawler-Based Search Engines Crawler-based search engines create their listings automatically. They "crawl" or "spider" the web, then people search through what they have found. If you change your web pages, crawler-based search engines eventually find these changes, and that can affect how you are listed. Page titles, body copy and other elements all play a role. Human-Powered Directories A human-powered directory depends on humans for its listings. You submit a short description to the directory for your entire site or editors write one for sites they review. A search looks for matches only in the descriptions submitted. Changing your web pages has no effect on your listing. Things that are useful for improving a listing with a search engine have nothing to do with improving a listing in a directory. The only exception is that a good site, with good content, might be more likely to get reviewed for free than a poor site. Existing System :- The current system is a browser which is completely related to internet browsing, which needs a complete security problem, but allows the user to list, pause, resume or restart the downloading of files. It also keeps history of recently downloaded files and allows opening them from within the browser. The Current system has automated method of collecting information is rather crude, and information can be out of context. The current search engines may produce out of date sites and often funded by advertising. Limitations in Existing System Displays only related web sites URLs. It works only on online web sites. It doesn’t show any related documents. Proposed System The proposed system develops a Search Engine that is of importance to either an organisation or a college. This Intranet based stand-alone application can be accessed through a web browser or e-mail. This application gives the search results for the “keyword”. Advantages over Existing System ü Mainly it is useful for colleges or any organisations as intranet based search engines. ü User should be able to search for the “keyword” in all file formats. ü User should be able to search other sites to search documents. ü User should be able to send a mail to the site and Search Engine should send back the top 20 search results back to the user. ü User can send one of search results to the site to fetch back the appropriate document. ü User should be able search documents on ftp sites as well. ü Indexing of the search sites should be periodic. ü The search results would be displayed using paging logic.
