I find the placement of notindexed: a bit cumbersome - has to be right before content:
I think it would be better to allow it as a global modifier I.E: ::notindexed: as searching for something in indexed content yields nothing, the next natural step for me is to search for the thing in files that are not indexed.
So instead of moving the cursor back to content: and then typing, I could just carry on typing: ::notindexed: afterwards...
Hope it doesn't sound too anal

Thanks
