I have a URL string which I don't want to be indexed. it includes the characters _Q1 ni the middle of the string.

So in the robots.txt can I use 2 wildcards in the string to take out all of the URLs with that in it?  So something like /_Q1.  Will that pickup and block every  URL with those characters in the string?

Also, this is not directly of the root, but in a secondary directory, so .com/.../_Q1.  So do I have to format the robots.txt as //_Q1* as it will be in the second folder or just using /_Q1 will pickup everything no matter what folder it is on?

Thanks.
