How to filter out numbers from text documents I have several text files that have numbers in them.  It would be very difficult to filter out all the numbers by creating a Stop Word txt file with every number from 1 to 2010, plus very inefficient use of resources.  Is there a way in Orange to parse out all numbers from text documents?
Yes, orange has regex abilities as seen here.  If you're unfamiliar with regex here's a link regarding regex with numbers.  The idea is pretty straight forward.  Use regular expression to find all numbers, then replace the numbers with something like a blanks string a placeholder word like "NUMBER".
