Modified Htaccess - Will it cause search ranking issues?

I noticed today that I was able to view the folders of my wordpress site's wp-uploads and wp-contents fully as a directory and view all files that were in these directories via browser.

I read that I should add 'Options -Indexes' at the end of my htaccess file, which I have done and it has rectified this issue.

I was wondering whether this command will affect search engine bots such as Google?
