A good library research topic usually contains 2-3 concepts. It is often in the form of a research question or statement.
Topics with only 1 concept or many concepts are hard to research.
Look at these examples for how to break a topic into concepts. We will use the concepts as keywords. See how the outcome changes when you have more or fewer concepts in a search topic:
Topic |
Number of Concepts |
Outcome |
Good: Impact of obesity on the development of Type II Diabetes |
obesity and Type II Diabetes= 2 |
9,928 results in [[CINAHL Plus with Full text]] database |
Good: How do high school dropouts rate their self-efficacy? |
high school and dropouts and self-efficacy= 3 |
45 results in [[ERIC]] database |

Bad: Do conflicts with 9th grade homeroom teachers result in students in Boston dropping out of school? |

Be Aware: Are you trying to support your personal opinion? Scholars focus on measurable research, and work to avoid bias. Your opinion may not be researched, or the research may support a different conclusion.
Breaking your topic or research question into keywords is your second step after you define your topic.
Pull out the words that indicate the main concepts of your topic.
Example:

Keywords are the search terms that you enter into the database to describe the topic of items that you want to retrieve. The database will word-match your keywords against the text of the article, and deliver results that match what you enter.
You can tell the database how to look for those words:
The great benefit of keyword searching is the precision. You can develop focused, precise searches in a library database, and get exactly what you need. It just takes some practice to become an expert searcher.
The databases can only word match. Databases look for the exact words and phrases you type in.
This means you must:
Most databases have multiple search boxes near the top of the page. Use them to enter each of your core concepts separately. Here is an example of how to set up a keyword search using the terms in the Pick Keywords box above.
1. Type in your keywords.
First search box:
malpractice
Second search box:
nurse manager
2. Click the Search button.
Tip: If you don't see enough boxes for your keywords, look for an Advanced Search option.
