Make :Ag not match file names, only the file content

Since there is a command :Files that can search files by name, I'd like to configure :Ag to only look at the file contents, not at the file names.

I'll demostrate my case below, my question is: can this be achieved today, maybe with some configuration?

---

To see why this is an annoying issue, create a file called demo.txt, put 20 lines each having a random number, and on the 21st line write demo. Then use :Ag demo to search for this string.

Expected: you find only one occurrence.
Actual: you also find 20 irrelevant occurrences.

Try this:

command! -bang -nargs=* Ag call fzf#vim#ag(<q-args>, {'options': '--delimiter : --nth 4..'}, <bang>0)

It looks like magic, but works beautifully, thanks @junegunn! 🎉

I'm trying to figure out how to run that command on startup. Any tips?

[backdoer]

Put it in your .vimrc @mbylstra

🤦‍♂️ I thought I had to prepend it with autocmd which wasn't working. Thanks!

Is it possible to combine this with my current Ag tweaks?
I have the following:

command! -bang -nargs=* Ag
  \ call fzf#vim#ag(<q-args>,
  \                 {'options': '--delimiter : --nth 4..'}, " Can't add this
  \                 <bang>0 ? fzf#vim#with_preview('up:60%')
  \                         : fzf#vim#with_preview('right:50%:hidden', '?'),
  \                 <bang>0)

@junegunn could you please help, is it possible to combine preview options with search only by files with Ag?

[junegunn]

* fzf#vim#with_preview([[options], preview window, [toggle keys...]])

So you have to write

fzf#vim#with_preview({'options': '--delimiter : --nth 4..'}, 'up:60%')
