All searches are case-insensitive.
For the acronym search you have the options to search exact or fuzzy . Exact search Exact search will find acronyms all of which match exactly the characters you type in. DDE Dynamic Data Exchange Fuzzy search Fuzzy search will find any occurence of the characters you type in, should it be in the acronym itself, in the expansion or even in the reference link. For that reason you cannot use diacritics in the term you search for. Because some acronyms are not unique in style, the acronyms in V.E.R.A. do not contain any speacial characters, only characters and numbers are used.
