How to make Mac OS X "find" feature local to application window

Mac OS X El Capitan 10.11.5

Sometimes I open up multiple windows of TextEdit and multiple tabs on Chrome and use the Cmd-f to find certain text. In each window, I'm looking for different texts. However, when I switch between the windows, the search text automatically transfers itself to the next window, and I lose my previous search results.

How do I make Cmd-f search text local to the application window, and not transfer itself when I switch between windows?

For example:

1. In Chrome - tab 1, I searched chickens. 300 results show up. I scrolled to the 150th.
2. In Chrome - tab 2, I searched eggs
3. When I switch back to tab 1, the search text automatically switches from chickens to eggs!

I have to enter chickens with Cmd-f all over again, and it might just start again from the 1st result, and I have to press Enter 149 times. So far this behavior has happened when switching between chrome tabs, between Chrome and TextEdit, and between TextEdit windows.
