Question about using glob pattern with rg

[senthil1216]

I am a new beginner user to Emacs.
Can someone point on how to use rg.el along with glob patterns to include or exclude dirs?
This is the command i have been using

M-x rg RET
Regexp search for (default -*-): SEARCH_PATTERN -g *.txt

But i get the results as
rg finished with no matches found at Fri Apr 21 10:23:12

Normally you us the ripgrep type flag, iow using predefined file types that could include one or more glob pattern. If you want to use custom glob patterns you just insert that in the file type prompt instead of the predefined rigpgrep type. See https://rgel.readthedocs.io/en/2.2.1/usage.html#file-type-aliases
ripgrep has the --glob flag for more advanced including and excluding of files dir. It's available from the rg.el menu but you have to consult the ripgrep manual how to use it.
