I have a list of strings like list1={{"a", "b something", "a", "a", "b", "c", "b"} In this list, 'something' is a sting that I will not know in advanced and there are several spaces between the 'b' and the 'something' in one string. The number of the spaces is unknown. I want to find out the position of the this "b something" sting in the list. So, I did, Position[list1, "b*"] and I also tried, Position[list1,"b"~~___ ] both of them gave me {} as results. Also Cases[list1,"b"~~___] or Cases[list1, "b*"] does not work. I can get the correct position only if I give the exact "b something" as the searching pattern. What is the easiest way to search with a incomplete string pattern in this case? Thanks for your help.
