Spotter feature idea/request - exclusion filter

I had a poke at this but couldn't find my way into how Spotter filters work, 

so I'll just pass on the idea.

Wanting to look at implementers of  #withIndex*

several tests are mixed in the result that it would be nice to eliminate 

by typing "subtract test" like this... " -test "

much like I'd do in google search.
