Quick way to find text for a file?

[laka]

to put it simply, when I try to search term for a file, I do this:

1. open the text file
2. press ctrl + f
3. input the search term in the dialog box (e.g. [\x{200b}-\x{200f}]) ; this searches hidden zero width character
4. press enter

this works but is not ideal. after doing the search with various search terms, the drop-down list that shows recent search gets longer and longer and when the allowed search history limit(10 as default) is used up, I should do the step 3 again manually. I can up the limit but still I have to scroll top to bottom to find what I need.

maybe it would be great if I can assign hotkey to search specific term I want found, or there's some tricks to add favorite search string somewhere in the program.
or some command line script or plugins to get the job done?

thanks
