Defining the Terms

Search Engine: A web page that contains an interactive form which allows you to work with a database of information. The database responds to your request by listing sites which match your search criteria. The database of a search engine is created by spiders (also known as crawlers or robots). A spider is a software program which scouts the internet looking for new web sites. Spiders typically index the URL, title and header sections of a web page.

• Use a search engine when hunting for specifics or the proverbial needle in the haystack.
• Alta Vista is an example of a search engine with 140 million indexed pages. It is refreshed every 28 days.

• Use a search directory when browsing for information. Browsing involves looking for a general area of interest and then narrowing the focus based upon what catches your eye.
• Yahoo is an example of a search directory. At the present time it contains 750,000 listings.

1. Read the instructions

2. Make your keywords specific

For example, input "drag racing" or "stock car racing" as opposed to "auto racing"

These are connectors or operatives that make the keyword request more specific.

• mustang AND convertible AND 1965 connects the three words in the search
• mustang NOT horses AND convertible connects mustang and convertible but excludes any pages that include horses
• "Randy Hanson works in an office." would list web pages that include the exact phrase within the quotations.
• + = AND   - = NOT
• * Use the asterisk as a wild card
• Used at the end of a word, the asterisk (*) is like a wild card and can replace up to 5 characters. It allows you to broaden your search by including plurals, adjectives and adverbs.
• For example: typing french english translat* will retrieve documents with the words french, english and translate, translation, translator and so on.

• What is a natural language query anyway?
• Searching using sentences or questions.
• Why shouldn't we use natural language?
• Keyword searching is faster.
