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? Under the "Databases By Title" tab, click the 'i' next to each database to learn its discipline scope and date range.

2. Try going to "Databases By Subject" in the COD Library's Databases page

   Click on your general subject area (History, Biology, etc.) This will generate a list of good starting points in your subject.

3. Try drilling down through the "Research" section of COD Library's website.

   They're set up like Yahoo! and similar Web sites, which means you have to know what general field your subject falls under (Social Sciences? Sciences? Interdisciplinary (2 or more disciplines)? Government and Law?) Try a few of these and see where you can find your subject. Then try using some of the databases you find linked there.
