Find or Create a Custom Search Engine

A rewrite engine is a piece of web server software used to modify URLs before fetching the requested item, for a variety of purposes. This technique is known as URL rewriting. In Java, the term "URL rewriting" is sometimes used to describe a Web Application Server adding a session id to a URL when cookies are not supported.

URL (Uniform Resource Locator), an address that points to a particular document or other resource on the Internet, used most frequently on the World Wide Web (WWW).

Keeping URIs so that they will still be around in 2, 20 or 200 years is clearly not as simple as it sounds. Web crawlers in an automated manner are bots performing URL normalization in order to avoid crawling the same resource, hyperlinks, and seedlings more than once and through endless combinations of relatively minor scripted changes in order to retrieve unique content.

Only alphanumerics [0-9a-zA-Z], the special characters
"$-_.+!*'(),"

[not including the quotes - ed]and reserved characters used for their reserved purposes may be used unencoded within a URL.

HTML, on the other hand, allows the entire range of the ISO-8859-1 (ISO-Latin) character set to be used in documents - and HTML4 expands the allowable range to include all of the Unicode character set as well. In the case of non-ISO-8859-1 characters (characters above FF hex/255 decimal in the Unicode set), they just can not be used in URLs, because there is no safe way to specify character set information in the URL content yet [RFC2396.]

URLs should be encoded everywhere in an HTML document that a URL is referenced to import an object (A, APPLET, AREA, BASE, BGSOUND, BODY, EMBED, FORM, FRAME, IFRAME, ILAYER, IMG, ISINDEX, INPUT, LAYER, LINK, OBJECT, SCRIPT, SOUND, TABLE, TD, TH, and TR elements.)

Once you've designed an icon, reduce the size to a square 16 x 16 pixel size. Second, download an icon editor such as IconEdit Pro. Third, open your file in the icon editor and tweak it until it is perfect. Save with 16 colors as favicon.ico and upload it to each of the directories in your website. Now every time an MSIE 5.0+ user bookmarks a webpage in a directory containing favicon.ico your icon will show up in their bookmark file.

A favicon or an urlicon, is an icon associated with a particular website or webpage. A bookmark is used to describe a method of marking a page so it can be referenced at a later time without having to remember the address. Browsers that support favicons may display them in the browser's URL bar, next to the site's name in lists of bookmarks. Another common problem is that the favicons may disappear if the browser's cache is emptied.

Bookmarks and Favorites save Web addresses so you can return to them quickly, without having to retype them. Whether you are using Mozilla Firefox, Netscape Navigator or Internet Explorer, the procedure is similar.

In your netscape window click on bookmarks and select edit bookmarks. A window similar to the oneon the left should appear. The items in this window represent your bookmarks. If you use Internet Explorer 5.0 or later releases, click on the Favorites button on the toolbar to open the Favorites window.

Del.icio.us was purchased by Yahoo! and is probably the most popular social bookmarking tools online; magnolia.com takes you to Exxon-Mobil; Furl is one of the oldest social bookmarking tools online and is owned by the Looksmart company; Many librarians use Furl and the system's users are very loyal; Markaboo is open source, under a Creative Commons license. You can take photos from a mobile device and SMS them... Traditional means of organizing information elements have generally relied on well-defined and pre-declared schemas ranging from simple controlled vocabularies to taxonomies to thesauri to full-blown ontologies.

Internet search engines are categorized by topic, searchable directory of general and specialty search engines, resources and tools for exploring the deep web, performing advanced research, and for learning about using search engine tools and technology.

Categories and Web search don't often go together. No search engine contains everything available since crawl rates use term suggestion tools as from the Google Directory results appear incorporated into result sets from the main database. Or primary crawls only accesses HTML material when the Google spider retrieves the URLs that appear on the HTML pages in a second crawl. AllTheWeb uses a specialized crawl of the Web to build catalogs to primary search result sets.

Instead of ranking potentially useful pages against all other pages in the database, Teoma ranks results against other pages in the same "community" of pages. These "communities" are built dynamically, in real time.

An Advanced site search and code, sitemap, and navigation technology can be added to your website. In some cases, the content updates more frequently than general engines and should increase precision and lower recall.

Once a keyword relating to the products or services offered is keyed into a search engine, a direct link to your web site should emerge on top of the list as soon as the user hits the Enter button or clicks on 'Search.'

A person might find it to difficult use the scroll down option so you should also provide hyperlinks which are accessible to them. The domain name may be followed by the path, a list of additional names that identify subdirectories within that domain. The path may be followed by a specific document name. URLs are case-sensitive, which means that uppercase and lowercase letters are considered different letters.

Make your website more search engine and user friendly, helping you to appear in the top listings in search engines.

Spiders can read the following items on a web page, thus making the item highly relevant to search engines: text, page titles, meta tags, meta descriptions, code, tables.

HTML hyperlinks are life-giving food for Search Engines' hungry spiders. They lead to major inside pages or web site sections.

Query results in search engines, or the matches found by a search engine to the keywords entered by the user, are important because of the fact that these are the most effective tools through which users try to access information on the Internet.

There is a shift occurring in computer text representation. Traditionally, text is represented by a single character of data (1 byte or 8 bits) at its lowest level. This allows for 256 possible distinct characters. In languages where the entire character set exceeds this range (such as in Far East languages) two characters are used to represent a single character.

The Unicode standard was developed to greatly reduce all this fracturing of languages into conflicting character sets. All major character sets of the world can be represented using a total of only about 35,000 of these character code points in the unicode set. The most popular version of this translation mechanism in use is UTF-8.

On the Internet, the most ubiquitous bots are the programs, also called spiders or crawlers, that access Web sites and gather their content for search engine indexes. A bot is a piece of software that compromises a computer. Keep your operating systems and applications fully patched. Check your browser preferences and downloads and turn Javascript on. The backdoors installed by bot software aren't easily removed and require that a computer be rebuilt.

The largest use of bots is in web spidering, in which an automated script fetches, analyses and files information from web servers at many times the speed of a human. Each server can have a file called robots.txt, containing rules for the spidering of that server that the bot is supposed to obey.

A spambot is an internet bot that attempts to spam large amounts of content on the Internet. Bots are also used to buy up good seats for concerts, particularly by ticket brokers who resell the tickets.

Bots are often used to farm for resources that would otherwise take significant time or effort to obtain. Another learning experience is trying to get your bot to grasp and understand natural human language and respond to it appropriately. The combined work of the entire community may prove to exceed what has already been done.
