The same command in the related TextWrangler returns a record containing
at least a 'found' property, whose value is a boolean.

  tell application "TextWrangler"
    set findResult to (find sigfindname searching in text 1 of text document 1 options {search mode:literal, starting at top:false, wrap around:false, backwards:false, case sensitive:false, match words:false, extend selection:false} with selecting match)
    if (not findResult's found) then
      display dialog "\"" & sigfindname & "\" not found" buttons {"Cancel"} default button 1 with icon stop
      -- error number -128
    end if
  end tell
