Using more fields impose a progressively restrictive search (i.e.: only show the entries where Country is the one requested AND keyword is the one requested AND ...).

The entered strings must be at least 2 characters long.

Entries for the Institution name and Activities fields will be parsed as strings being part of the whole name/text.

Characters with modifications (such as acute, grave, tilde, ümlaut) should be searched without modificator (eg: niño -> nino, für -> fur)
