Regex To Filter Any Word In Any Order In Column Of JTable?

I created filters for every column in my Jtable however, some of these columns have more than one word inside of them and my filters will only filter them based on the first word. For example if I had a first and last name in one column, it will filter the table if I enter the first name in my filter text field but it will not filter that same column if I only input the last name. What is a good regex expression to filter any word in any order?

public static void filterRows() {
String filterId = idFilter.getText();
String filterFrom = fromFilter.getText();
String filterTo = toFilter.getText();
String filterCC = ccFilter.getText();
String filterDate = dateFilter.getText();
String filterSubject = subjectFilter.getText();
