Database technology has not yet advanced to the Star Trek level which would allow you can talk to a computer as you would to a person and have it understand exactly what you mean.
A keyword search allows a human to tell a database what they are looking for in a way that makes it easy for the database to respond. To create a keyword search, select the words and/or phrases that are the best match for the topic. Be aware that the keyword search you begin with will most likely require changes in order to retrieve the most useful results and not so many results that you are overwhelmed. This is absolutely normal. It also makes the best use of your research time since it allows you to zero in on relevant articles more quickly than going through screen after screen of disappointing results hoping to spot something good.
