I am facing the same problem right now with exactly the same principle you are aiming for. After a long search, I finally came to this:

[HttpPost]
public ActionResult Index(string searchString){
    searchString = searchString.Replace(",", ".");

    if (!String.IsNullOrEmpty(searchString)){
        students = students.Where(s => s.FIRST_NAME.Contains(searchString) 
        || s.LAST_NAME.Contains(searchString)
        || s.PERSONAL_NUMBER.Contains(searchString)
        || s.ACD_UNI_DEGREES.DEGREE.Contains(searchString)
        || s.ACD_UNI_FACULTIES.FACULTY.Contains(searchString)
        || s.ACD_UNI_SPECIALIZATIONS.SPECIALIZATION.Contains(searchString)
        || (s.SEMESTER.ToString()).Contains(searchString) 
        || s.COR_PAYER_STATUS.NAME.Contains(searchString)
        || SqlFunctions.StringConvert(s.CREDIT_COUNT).Contains(searchString));
    }
    return View(students.ToList());
}

You are casting the decimal to string normally with ToString(). However the bracetts are the magic weapon here: (s.SEMESTER.ToString()) this makes a difference.

This syntax will allow you to search with the notation . (Example: 1203.4 instead of 1203,4). Which is not really user-friendly.

To solve this, use the .Replace(',', '.') on your searchString. This will apply the trick on background and no one will notice.

I hope it helped anyone struggling with the same problem.
