I have an online application which has an internal feature that returns blocks of text.  You can think of this page almost like a search-results page.  Depending on the input variables, different combinations of text will be returned.In other words, this 'results' page is not necessarily unique text.   Multiple different input variables, may return very similar text output, or repeated text output.Is it best just to tell Google to ignore this page entirely?
