How do you use the search engine?
Here you will find some useful tips on how to use the search engine.
When you enter the search term in lower case, the search engine will find both
upper and lower case instances of your search term.
When you enclose the search term in double quotation marks, a search will be
made for this specific chain of characters (example: "health risk")
If you want to search for several keywords, enter each one followed by a space
(example: food risk man).
Extend the search by linking your search term with the operator 'OR' (example:
diseases or infections)
Narrow the search response by linking your search term with the operator 'AND'
(example: bacteria AND food)
Exclude keywords by preceding them with the operator 'NOT'.
With the symbol '*' you can search for word roots (example: Vitamin*)
