★★ HELP WITH SEARCHING ★★\n\n◙ I used to have so much trouble finding what I wanted. That's because I didn't know the best methods for filtering my searches. Now I rarely have trouble finding what I want. Thanks to a great web site called GoogleGuide. Click on the "Novices Click Here" button to read about Google's fantastic search syntax. Yahoo has some of these operators too. But not even close to the amount that Google has. Below are a few examples.\n\nsite:briefcase.yahoo.com (mp3)\nintitle:?parent directory? (mpg|avi|wmv|mov) "strauss"\ninurl:forum intitle:recipes intext:cookies\n\n☞ http://www.googleguide.com/\n\n◙ Some of what you will learn at the GoogleGuide was used to create the following special search tools.\n\n☞ http://www.soople.com/\n\n◙ Compare Yahoo and Google search results in side-by-side frames here.\n\n☞ http://www.gahooyoogle.com/\n\n◙ You'll get pretty much the same tutorial as the GoogleGuide has by reading the first few chapters of this book.\n\n☞ http://tinyurl.com/6zx2\n\n◙ Here are two more great sites to help you.\n\n☞ http://tinyurl.com/qey8v\n☞ http://tinyurl.com/2ywye\n\n◙ You shouldn't rely on just one search engine. There are many really good ones and they don't all have the same things in them. One might have links to HTML sites etc. and another might not. There are currently 800,000 search engines. Most of them are specailty search engines. Here are several hundred generalized search engines. Plus a few specialized search engines I threw in for my own use.\n\n☞ http://dwight.clickthesky.com/search/\n\n◙ Google is the very best full-text search engine. But when you want a much deeper search you should use the number one cluster search engine.\n\n☞ http://www.vivisimo.com/\n\nIf you are in a really big hurry you can search many search engines at once by using meta search engines. These will give you the top-ten most-relative results of each engine they search.\n\n☞ http://www.ask.com/\n☞ http://www.msn.com/\n☞ http://www.dogpile.com/\n☞ http://www.altavista.com/\n☞ http://www.webcrawler.com/\n\n◙ Here is a way to search many different search engines from a single portal. I use this everyday to research your questions before answering them. Select a resource from the dropdown menu, type in your keywords, and click search.\n\n☞ http://www.searchalot.com/

Designing a good search engine involves a lot of planning. The different components of a search engine are:\n1. A Bot / Crawler program that scans different websites and extracts the content.\n2. A parser program  that eliminates the HTML tags and other words that you dont wish to store.\n3. An Index - which is a list of keywords and link to the URL in which this was found.\n4. A Ranking algorithm that can assign some kind of weightage to the entries in the index to identify which entry in the index is more relevant for a keyword. This could get very complex so that the context of the content, relevancy, freshness, reliability of the content and many other factors are considered before a ranking is done.\n5. Storage architecture - The index could grow to phenomenal sizes (more so if not planned well) and so you need to decide what kind of storage you wish and how data can be retrieved quickly from many physical stores.\n6. A Web interface to query the index and display results appropriately.\n\nI'm no Guru in search engine tech - but briefly this is my understanding. Good luck!

Dear Andy,\n\nLike all things made by humans, Internet is also not perfect. Search engines work on a fixed alogorithm and aritificial intelligence. They crawl the net looking and indexing pages depending on the keywords, relevence etc.\nAnd people have found ways to optimise their sites to get better search engine coverage and what is known as "page rank" in Google.\n\nThere are many Search engine optimiser companies which do this type of work.\n\nMore exact details refer to this URL :\nhttp://www.google.com/webmasters/seo.html\n\nHope this helps.\n\nAmit

http://en.wikipedia.org/wiki/Main_Page just like paper encyclopedia only better\n \nwhat a search engine does is spider the net and look for web pages with key words in them that the rank  then when you look for something with the keyword in the document  it will display a list of document where the key word was found.

A web search engine is actually a database in which talks to the web browser client through the web server.\n\nThe first search engine is www.webcrawler.com\nsee: http://www.webcrawler.com/info.wbcrwl/search/help/about.htm\n\nYou can build a database with a web server on your home computer and write your own type.\n\nTake a look at:\nhttp://www.allsearchengines.com/\n\nOnce you have built your search engine you will have to do a lot of other things such as register a domain, find a provider, get the word out there..\n\nDo some searches on the history of search engines and meta data etc.. there are many layers to doing this.\n\nHope this helps.

When a search engine crawls a page it checks for relevancy between the meta tags in the head of the page, and it's connection to actual text within that same page.  It also checks the links to other pages and crawls them for the same information.\nIf you have a meta tag that defines the page, and then no text to match that tag, it will not keep that information due to the lack of relevancy.  Meta tags and keywords can be a bit confusing, but they are exactly what the search ingines use when crawling a site.  The only info stored by the search engine is the Title and Description as well as the link to how to get to that site. Hope this helps

(1) The search string you entered was probably entered by someone long before you. So google records this string and the pages that were visted out of the list that was displayed. Next time somebody enters the same string or similar search the most visted sites appear at page 1and calculates a number of probabilty of further search and therefore declares how many pages there might be.\n(2) Google caches universal webpages every four hours (may be even less). This gives it the edge to search on a blink of an eye.

How would you ever find anything on the internet without some way to search it?\n\n~ ♥ ~

Contact the sources of the information, not the search engine. The search engine is searching for certain strings of information, such as a name. If anyone has your name, they're information may come up in your search. Find out where the search engine found the information and contact that institution to get it removed or fixed.

No, Yahoo! uses their own search engine. The difference is that whereas Google will index pretty much anything it finds on the web, the Yahoo! search engine is more selective. It will only index websites that have unique content. (It also tends to rank pages on Yahoo! higher.)

A search engine is normally an automated computer that "crawls" the web looking for pages. All the pages it finds are put into an index with key information taken from the title of the page, keywords, meta tags, and the copy on the page. People can then use keywords to search the index for any matches.\n\nA Directory is normally a hand built, human edited system, where people review each site individually before adding it into the correct category (or subject area). Users can either browse the directory by clicking through different categories or can search the directory for specific keywords.\n\nThe advantages of a search engine are that they are often more up to date with breaking news and new sites and have a much wider range of sites in their index.\n\nThe advantage of a Directory is that each site is normally good quality as it has been checked by a human and is less prone to being "spammed" by unscrupulous site owners trying to artificially inflate their ranking.\n\nSearch Engines:\nhttp://uk.search.yahoo.com/\n\nDirectory:\nhttp://uk.dir.yahoo.com/\nhttp://www.dmoz.com/
