Perhaps you should try some spelling variations:
"economische gevolgen" » "oeconomische gedanken", "okonomische folgen", "economische groei"
"economische crises" » "economic crises", "economic crisis", "economische groei"
"economic crimes" » "economic crises", "economic crime", "economic crisis"

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (((("economische crises") OR ("economic crimes"))) OR ("economische gevolgen")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"economische crises\") OR (\"economic crimes\"))) or (\"economische gevolgen\"))".
• Removing quotes may allow a broader search: (((( economische crises ) OR ( economic crimes ))) or ( economische gevolgen )).
• Adding a wildcard symbol may retrieve word variants: (((("economische crises") OR ("economic crimes"))) or ("economische gevolgen"))*.
