Search something in sub-directory only
Recently I worked in a giant Rails monolith repo. When I say giant, it means multiple teams owning different modules inside the rails, and there are thousands of files.
As a result, doing +ivy/project-search is not efficient because it
searches the entire project and shows too many irrelevant results.
Because most teams touch files in a sub-directory only, we could narrow the search to a sub-directory, which makes the search more useful.
My solution: C-u counsel-rg.
With the prefix, the command asks for the input of a folder first. If
you visit a sub-directory often, use M-p to go to previous input
without typing.
It then shows the hits of files under the sub-directory only.
It is based on ripgrep, so it supports regex based filter (Credit:

For example, search keyword in jsx files only:
keyword -- -g\*.jsx
From there on, we can do C-c C-e to do bulk edits or search & replace
to deal with the results.
