  40. Search Services Web Portal A Web portal is a single point of access to information which is • Linked from various logically related internet based applications and • of interest to various type of users • Portals present information from diverse sources in a unified way. They provide an excellent way for enterprises to provide a consistent look and feel with access control and procedures for multiple applications, which otherwise would have been different entities altogether. • Examples are Yahoo, MSN

  41. Search Services Search Engines • Google – • Yahoo! Search • Yehey! • Altavista – • Hotbot – • Excite – • Ask –

  42. Search Services How do search engines work? • Search engine databases are selected and built by computer robot programs called spiders – crawling on the WWW. • They cannot think or type a URL or use judgment to "decide" to go look something up and see what's on the web about it. (Computers are getting more sophisticated all the time, but they are still brainless.)

  43. If a web page is never linked to in any other page, search engine spiders cannot find it, unless its URL is sent to the search engine companies as a request that the new page be included. • After spiders find pages, they pass them on to another computer program for "indexing." Text, links, and other content in the page are stored in the search engine database's files so that the database can be searched by keyword and whatever more advanced approaches are offered, and the page will be found if your search matches its content.

  44. Ranking of websites • Word proximity and placement • Popularity - a link to a page is a vote for it • Importance - traffic, popularity of pages linking to a page • Subject specific • Some types of pages and links are excluded from most search engines by policy. Others are excluded because search engine spiders cannot access them. Pages that are excluded are referred to as the "Invisible Web" -- what you don't see in search engine results.


  46. Tips on Searching the Internet • Choosing search terms • Multiple search terms • Phrases • Do not include common or question-oriented words like a, an, the, and what • Negative and positive terms • minus sign ("-") in front of words related to the meaning you want to avoid • plus (+) sign to that word or those words in your search

  47. Tips on Searching the Internet • Filter or field searches • intitle: • inurl: • site: • Boolean operators and parentheses • AND, OR, NOT or AND NOT, and ( ). Must be capitalized. • You must enclose terms joined by OR in parentheses (classic Boolean). • Note: ( ) or nesting is not available in Google or Ask

  48. Tips on Searching the Internet • Quotation marks (“ “) • - put around the search terms that you want • Truncation (*) • - ex. develop* - searches phrases or sentences that contains develops, developed, developing, development • Hyphenation in between words • - searches all forms of the term, whether spelled as a single word, a phrase or hypenated

  49. Tips on Searching the Internet • Similar words (~) • - searches for a word and all its synonyms • Number range search • - Follow search terms with beginning and ending numbers, separated by two periods. • - Can be used one sided, as less than or greater than • Limiting searches to filetypes • - filetype: or ext: • Definitions and encyclopedic lookups • - define:

  50.
