```
public static String specialToLowerCase(String str)
```
    the database lower() function in PostgreSQL only works for ASCII strings. All other unicode and multibyte characters like capital umlaut are not properly converted. At the moment, when searching for pages we do the following comparison:

    This special lower case function will skip the JAVA .toLowerCase() for postgres whose database lower() is ineffective.
    
    Parameters:
    
    str - the string to convert to lower case
    
    Returns:
