السلام عليكمWhat Are "Meta-Search" Engines? How Do They Work?In a meta-search engine, you submit keywords in its search box, and it transmits your search simultaneously to several individual search engines and their databases of web pages. Within a few seconds, you get back results from all the search engines queried. Meta-search engines do not own a database of Web pages; they send your search terms to the databases maintained by search engine companies. ==محركات البحث المتعددة عندما تقدم كلمات البحث في صنوق البحث لديها هي ترسله بشكل آني لعدة محركات بحث اخرى فردية لها قواعد بينات خاصة بكل منها..خلال بضع تواني تعود النتائج من كل محرك بحث على شاشة واحدة وفرها محرك بحت الميتامحركات بحث الميتا لاتملك قاعدة بيانات خاصة بها وانما تعتمد على قواعد بينات محركات البحث التي تسألها---------------Metasearch enginesThere are also "metasearch" services like Search.com, GO2NET's Metacrawler and our own Pandia Metasearch engine. They search several search engines and directories at the same time, trying to extract the most relevant hits from all of them. You might find it useful to start your searching with one of these, just to get a general feeling for what is out there. The search syntax is problematic, however. It may vary from search engine to search engine, which means that the metasearch engine has to try to "translate" your query into a language that each search engine will understand. More often than not, they will not try to do so.For more complex searches, you should go directly to the relevant search engine. Also note that the metasearch engines will give you but a small part of the results from each individual search engine.----http://www.lib.berkeley.edu/TeachingLib/Guides/Internet/ToolsTables.html

Search enginesSearch engines are -- well -- "engines" or "robots" that crawl the Web looking for new webpages. These robots read the webpages and put the text (or parts of the text) into a large database or index that you may access. None of them cover the whole Net, but some of them are quite large. The major players in this field are Google, Yahoo! Search (which is not the same as the Yahoo! Directory), MSN Search and Ask. (A new version of Microsoft's search engine can be found at Windows Live.) Alta Vista and AlltheWeb are no longer search engines in their own right, as they are using results from the Yahoo! search engine. Yahoo! is also powering the Lycos portals, MSN Amazon.com's search engine A9, while Google feeds data to AOL and other portals. Search engines should be your first choice when you know exactly what you are looking for. They also cover a much larger part of the Web than the directories.==محركات البحث لها قواعد بينات خاصة وضخمة تعتمد عليها من اهم مكوناتها robot= spidrerالعناكب التي تزحف الويب وتزور المواقع الجديدة وتفهرس الصفحات لتضيفها لقاعدة البياناتوعندما نبحت نحن حقيقة لانبحت في ويب وانما في قاعدة بيانات كل محرك لدا فمحرك البحت يتكون من عناكبفهرسقاعدة بياناتوواجهة بحث

Search directoriesSearch directories are hierarchical databases with references to websites. The websites that are included are hand picked by living human beings and classified according to the rules of that particular search service. Yahoo! is the mother of all search directories. However, in order to search the directory you must go to their special directory page.. Their regular search results are not fetched from the directory, but from their search engine. For obvious reasons we are very fond of the Pandia Plus Directory, which is based on the Open Directory, a catalogue compiled by enthusiasts from all over the world. Directories are very useful when you have no more than a general notion of what you are looking for. The first page normally gives you the most general categories (like "Computers and Internet" or "Education"). Click your way down the hierarchy to the right category, select the website you find the most interesting and start reading.If you use the search form when exploring a directory, remember that you are not searching the text of the actual webpages of a particular site. Instead you are searching the text contained in the site title and the description of the site. These are composed by the directory editors, and are often based on suggestions from the site owners themselves. In addition most directories will also search the words contained in the category titles or descriptions. Note, however, that some search directories may add data from regular search engines if they cannot find matches to your query. We will tell you more about this below. ===الادلة بشكل مختصر هي قوائم مرتبة ومنضمة هرميا او تدريجيا تحت عناوين رئيسية تم فرعية للبحث خلالها
