## Keywords

If you then choose your resource and it is a search engine or database, what will you enter in the search field? Which keywords? You often have to find out which technical terms are used in those information sources that you are trying to find. You can initially brainstorm from your search question:

- Which concepts are central to the question?
- Are there similar or broader / narrower concepts? (synonyms)
- Are the terms open for only one explanation?
- Are there relations between the terms used?

In addition to brainstorming from your initial question, you can ask an expert. You can also simply try out and adjust some keywords based on what you find. Once you have found something suitable, look at what words are used in that source! Last but not least: do not limit yourself to search keywords in your own language, but find out what the English terms are.
