Text filters in a Helpshift automation all rely upon the automatic comparison of two or more text strings. 
  • App
  • Forwarding Email
  • Tags
  • Title or First Message
  • Predict Label
Text filters all follow a uniform set of rules. 
  • When strings are not case sensitive — "book" matches "bOoK" 
  • When variants do not match — "book" does not match "books" or "booking"
  • When substrings do not match — "book" does not match "textbook"
  • When an underscore is a delimiter — "book" matches "old_book"
  • When a hyphen is a delimiter — "book" matches "old-book"
