Evaluating

Your Search Strategy

Here are some tips if you found too much information, too little information, or the wrong information in your search.

Too Much Information

1.

Try looking at an irrelevant record your search retrieved.
Can you figure out why the database gave it to you? Did you use one word that the computer misunderstood? See if you can use a more specific term or maybe a short phrase that excludes the meaning you don't want. Try adding a new term which makes your old term more specific.

Instead of

Japan and economy

Try

Japan and economy and (auto or automobile or car)

2.

Check where in the record your search terms matched. The best matches for topics are in fields like Subject or Title. Look for an Advanced or Expert Search option in the database to search in specific fields only, if you can.

3.

Use limiters when they're available. Will the database let you ask for publications only in English? Can you ask for only journal articles? Want more recent information? Is there a subject heading that covers your topic? Can you get rid of book and film reviews? Play around with your options and see if they help. Try using the operator NOT.

(Iran and Iraq) not war

Hussein and not Saddam

Clinton not Lewinsky

+Jazz -Utah

Too Little Information

1.

Did you spell your search terms correctly? Research databases are remarkable tools, but they don't come equipped with spell checkers. One misspelled word can sink an entire search. Check a dictionary.

2.

Get rid of long phrases. When you type in a phrase, all the words must appear in exactly that order before the database will give you anything. Some databases automatically put the operator AND between the words you type, turning your phrase into a long Boolean search string.

Instead of

discrimination against ethnic Chinese in Vietnam

Try

discrimination and ethnic Chinese and Vietnam

3.

Try using alternative terms. That's what you gathered all the extra vocabulary for. Don't forget truncation or wildcards for variant forms of a word.

4.

Try to come up with broader terms for the idea you need. Every so often, it happens that there's very little written on a specific topic, but a lot on the general area.

Very narrow

recombinant DNA and sheep

Narrow

cloning and animals

Broader

genetic engineering and animal*

Very broad

genetic* and animal*

The Wrong Information

1.

Check the coverage of the databases you're using. Do they cover the kinds of material you need? The right discipline(s)? The right kinds of documents? The right dates?

2.

Try the Library Research Guides linked from the EMU Library website.(there's a link in the right margin of this page.) This will provide many good starting points.

3.

Try using the list of library databases by subject which can be accessed from the EMU Library website under the Databases tab, to find other databases that might be more useful.
