You have found more information now and can start brainstorming about your topic. Write down all the search terms you have come across during the orientation phase. Also try to think of search terms using the knowledge you already have about the subject. (See the chapter Orientation on your topic).
Use the terms you have found in sources such as handbooks and reference works and do some more searching using these terms.
Use synonyms for the search terms you have found. Where possible, use different spellings of the search terms and use translations in case you want to use literature in other languages.
In some databases you can use a thesaurus to look for new search terms. In a thesaurus you will often find other terms (broader as well as more specific) that relate to the term you are looking for.
For more information on this, see the chapter ‘Searching and finding'.
If your search produces too many results, you need to make your search terms more specific. You can also add extra search terms. But make sure you do not exclude an important aspect of your subject!
If your search produces too few results, you need to broaden your search terms.
For more information on what to do if your search produces too many or too few results see the chapter 'Search techniques and search tips'.
