refined or given value

life Is a pre-computer activity Yields more reliable results

Quality not Quantity Must be taught

Why “searching” is essential? Complex, information-rich world Many good electronic sources Saves time Life skill for the next century

Searching demands that one: Ask questions Organize and assess information Master higher order thinking skills Demonstrate achievement Master strategies for solving

problems Identify best sources of information Determine when information can

help solve a problem

What Can We Learn?

Try a few, carefully chosen key words!

Tips for Searching

doctor

Single Word Search

How many words in a search?

Single word searches often lead to irrelevant “hits”

More keywords - the narrower the search - more relevant

Too many keywords may narrow it too far and not get anything

Search for Phrases

Search for Phrases Often the best way to get relevant

hits Sometimes phrases need to be

narrowed even more.

More Tips for Searching

Develop strategies before searching Brainstorm key words and synonyms If you don’t find it with one search

engine, try another Quality is preferable to quantity Use specific words when looking for

specific things (Porsche, not car or automobile)

Tips for Searching, cont.

Use a unique keyword or phrase (“Detroit tigers” or “Bengal tigers” instead of tigers)

Find out if case counts. (saints or Saints)

Watch your spelling

Tips for Searching, cont.

Refine searches as necessary AND to narrow, OR to broaden,

NOT to eliminate Generally first documents

displayed are best matches, so if you don’t find it on the first few pages,....try, try again!

Meta Search Engines

Search multiple search engines at once Use it for very obscure/narrow topics Examples:

WebCrawler Dogpile Metacrawler Yippy

Meta Search Engines

Advantages Queries multiple search engines Returns results simultaneously More Internet-wide results

Disadvantages Slower Most can’t use complex search statements Results sometimes overwhelming Some give duplicate hits

Directories

Human beings: View sites Classify sites Sometimes review and/or rate sites

Ideal for browsing broad topics Less comprehensive than search engines Less duplication Higher quality

“...a directory that is searchable, not a search engine….”

Yahoo!

Granddaddy of directory-based Web search tools

1994 @ Stanford by two Ph.D. students (who dropped out)

Hierarchical approach to organizing info “Hands-on” classification of submissions Not as large as

other search engines

Yahoo! is best when:

You have a broad topic in mind and need to narrow it

You want just a few really good sides on a particular topic

Portals

Want to be your “doorway” to the Internet

Most are personalizable Search tools - directories and search

engines Email Stock Quotes News

Web Watchers and Personal Spiders
