Data Find/Copy/Entry

Searching for required 'name' information from one website. Once found and filtered, copy and paste information into an Excel spreadsheet. Will probably filter to around 500,000 names with the relevent attached fields as required. Will require a methodical alphebetical search of the website's database of EVERY possible letter combination (from a set of 3 letters and spaces eg aaa, aab, aac, a aa, a ba, a ca, aa a, ab a, ac a) and so on so as not to miss any names. Unless you know of another way?
