The search engine is not case sensitive. This means that "Panayiotou" is the
same as "panayiotou". Also, bear in mind that everything typed in the text
fields above is interpreted as a single string. Entering "Andreas Nicos" will
not make the engine search for "Andreas" and "Nicos" separately. Whitespaces
at the begining and end of search strings are deleted.
To get more matches, you can try one of the following:
Use substrings (e.g. use "Andr" if you are searching for "Andreas")
Use the comprehensive search method to add more criteria
