Helm search function

helm-search-doc-ag.el

(defun helm-search-doc-ag ()
  "Search for a keyword in the Documents folder using ag"
  (interactive)
      (helm-do-ag "~/Documents"))

(global-set-key (kbd "<f5>") 'helm-search-doc-ag)

This does not search in subdirectories of ~/Documents. Do you know how to make it recursive? Thanks!

@AtomicNess123 I’m currently on holidays. Once I’m back I’ll add a comment on how to make the previous function recursive.

Thanks, and happy holidays!

You should set the following variable to allow recursive search of text files only

   ;; Allow to recursively search git repositories inside other
   ;; repository (text files only, binary files are ignored)
   (setq helm-ag-command-option "--all-text")

Thanks! Two questions:

1. This would set this option for all helm-ag instances and not just for that particular function?
2. This would only make it recursive for text files and not other files (PDF, DOC, etc.; I was interested in the latter)?

Another problem is that

(setq helm-ag-command-option "--option")

Only allows for one option.

If you try:

(setq helm-ag-command-option "--all-text, -g")

It won't work

Did you try to use?

(setq helm-ag-command-option "--all-text -g")

Thanks, it works!
One question though: According to the man page:

[-t](https://www.mankier.com/1/ag#-t) [--all-text](https://www.mankier.com/1/ag#--all-text)
Search all text files. This doesn´t include hidden files.

[-u](https://www.mankier.com/1/ag#-u) [--unrestricted](https://www.mankier.com/1/ag#--unrestricted)
Search all files. This ignores .ignore, .gitignore, etc. It searches binary and hidden files as well.

I wanted to search ALL files, and you suggested --all-text. Wouldn't it be -u (would search all files, not just text)?

@AtomicNess123 my previous comment was meant to show you how to concatenate options for ag. I didn't look at what -g does. If you wanna search all files you can use:

       -a --all-types
              Search all files. This doesn´t include hidden files, and doesn´t
              respect any ignore files.

or

       -u --unrestricted
              Search all files. This ignores .ignore, .gitignore, etc. It
              searches binary and hidden files as well.

depending if you want to exclude (-a) hidden files or you wanna include them (-u). I hope is more clear now :).

Thanks, excellent. So both of these options will include .gitignore files, I understand. Is there an equal option to search all files, hidden included, but not .gitignore files?
