Even Google has choices: Google Print - Search the full text of booksGoogle Print Google Scholar - Search scholarly papersGoogle Scholar Google Directory for a subject approachGoogle Directory Google Images
16
Review question # 3: And when you are in the search engine or database, did you know you have a major searching interface choice?
17
Simple vs. Advanced It’s about power!
18
Why go beyond the simple search screen?
19
Simple Screen Click here for more precision and power!
20
Advanced screen
21
Simple screen in a database
22
Advanced screen in a database
23
And within your database, you will often have to make another choice!
24
Another decision: Subject / Topic Keyword Full text
25
This is an important choice!
26
Review question #4 What is the difference? Subject / topic Keyword Full text When might you use each?
28
Use the language and structure of the database to gather relevant material! Subject headings or descriptors in databases
29
In some databases this choice is critical!
30
More about subject headings and database structure!
31
Databases have information hierarchies
32
Subject structure behind the database
33
Descriptors may look different
34
Some search engines also offer subject / topic cues or clusters
35
You can open these categories!
36
Search engine clusters help you find relevant documents and suggest search terms
38
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
39
Using stop or noise words instead of a Boolean operator List of English “stop words”
40
Review question # 5 What are Boolean operators?
41
Rockwell Schrock’s Boolean Machine http://kathyschrock.net/rbs3k/boolean
42
Google doesn’t care, but your database does! Google ignores stop words and assumes an AND between words.
43
How important AND is!!!
44
Using the operator “AND” gets more results!
45
When to use “+” in Google
46
When do you really need OR? OR is generally used for synonyms or related words.
47
OR in Google
48
NOT as a refinement technique for problem words eagles NOT Philadelphia “Martin Luther” NOT King
49
Using “not” in Google
50
Boolean operators in databases
55
“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
56
Time for parentheses?
59
Wildcards and stemming Google stems, it returns varies forms of words Many databases do not stem. Use an asterisk for various word forms adolesc* child* teen*
60
Using wildcards in databases
61
A question is not a query How many buffalo remain in the United States? Can you create an effective “two word” search? From David Barr, formerly of IMSA
62
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
63
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.
64
And just a few more little tricks!
