If you (or other people) are searching an area for something (in my case I'm searching for a number in a wide grid), and you get the searching area smaller.
What is the expression for that?
I'm not sure if I'm clear enough.
I googled and I got,
- "closing a search" : to stop looking
- "tightening a search" : I got nothing
So what should I use?
I'm going to use it like, ___ the search over a smaller area.
