I create a database that contains a table. 'Nachname' and
'Kongressbereich' are special fieldnames. This program can search for
a special letter. In my example it is 'G'. and the search takes place
Mow I want to use regular expression. So that I can limit my search.
For example: I can search for Ge and it is not relevant wich letters
