3.5 How to get more / fewer search results

It is best to search in such a way that you get a maximum of a few hundred search results, without missing anything relevant. 

If you get too many search results this is what you can do:

• Use more or different search terms.
• Refine your search results with the 'Advanced search' option.
• Use the filter options.
• Use the Boolean AND operator. The AND operator limits the search results.

If you get few or no search results this is what you can do:

• Use the Boolean OR operator. The OR operator expands the search results compared to searching for a single word.
• Use fewer or different search terms.
• Search more broadly.
• Try other sources.
