a crash courseThe stuff you need to

know about searching, but may have forgotten along the way!

(And, the stuff I want you to know before you go off to college!)

But we’ve heard this all

before, Mrs. V!

Sorry.This important review won’t hurt too much! I promise!!!! And it will help you in college and beyond!

Let us begin!Yeah! Okay. We love databases and searching!

And I love your enthusiasm for

searching and databases!

You make me proud!

Our review begins!

Review question #1:

Subscription or Proprietary Search Tools

Even Google has choices:

• Google Print - Search the full text of books

• Google Scholar - Search scholarly papers

• Google Directory for a subject approach

• Google Images

Review question # 3:

And when you are in the search engine or database, did you know you have a major searching

interface choice?

Simple vs. Advanced

It’s about power!

Why go beyond

the simple search

screen?

Simple Screen

for more

precision

and power!

Advanced screen

Simple screen in a database

Advanced screen in a database

And within your database, you will often have to make

another choice!

Another decision:

Subject / Topic

Keyword

Full text

This is an important choice!

Review question #4

What is the difference?

• Subject / topic• Keyword• Full text

When might you use each?

Use the language and structure of the database to gather relevant material!

Subject headings or descriptors in databases

In some databases this choice is critical!

More about

subject

headings and database structure!

Databases have information hierarchies

Subject structure behind the database

Descriptors may look different

Some search engines also offer subject / topic cues or clusters

You can open these categories!

Search engine clusters help you find relevant documents and suggest search terms

STOP the insanity!

Stop using stop words in your searches!

in, of, the, a, to you, why, who, what, on, than, then, their, an, his, her, be

Using stop or noise

words instead of a

Boolean operator

Review question # 5

What are Boolean operators?

Rockwell Schrock’s Boolean Machine

http://kathyschrock.net/rbs3k/boolean

Google doesn’t care,

but your

database does!

Google ignores stop words and assumes an AND between words.

How important AND is!!!

Using the operator

“AND” gets more

results!

When to use “+” in Google

When do you really need OR?

OR is generally used for synonyms or related words.

OR in Google

NOT as a refinement technique for problem words

eagles NOT Philadelphia“Martin Luther” NOT King

Using “not” in Google

Boolean operators in databases

“Phrase searching”

• One of your best searching tools!• Use only for legitimate phrases, names, titles

• Best example -- “vitamin A”• “John Quincy Adams”• Titles “An Officer and a Gentleman”• “to be or not to be”

• Phrase searching is sometimes overused: not every group of words is a phrase

• Sometimes “ANDing” is a better strategy

Time for parentheses?

Wildcards and stemming

• Google stems, it returns varies forms of words

• Many databases do not stem.• Use an asterisk for various word forms

A question is not a queryHow many buffalo remain in the United States?

Can you create an effective

“two word” search?

From David Barr, formerly of IMSA

How to structure a good query• Brainstorm several key words and

phrases—the ones you think would appear and wouldn’t appear in your dream document

• Anticipate synonyms and related words

• Mine your results!: be on the look out for better words and phrases as you search

More on the query

• Focus on nouns (verbs are often vague, stop words, like articles—a, an, the—are ignored by most engines)

• Include most important words and phrases first.

And just a few more little tricks!
