I've tried to add the item below in .htaccess(wamp64\bin\apache\apache2.4.37\conf) and enabled Use URL Rewriting in Joomla however when I try to type abc.com in search engine address bar it will still redirect me to search page instead of redirecting me to the website. I've also performed checking and confirmed that .htaccess file is readable, the webpage is work when go to https://www.abc.co m however redirection still not work. I just need the page to redirect from http://abc.co m to https://www.abc.co m Is there any other way to do it? Or I'm doing it wrongly?? Please help.
RewriteCond %{HTTP_HOST} ^abc.com [NC]
RewriteRule ^(.*)$ https://www.abc.co m/$1 [L,R=301]
The redirect itself works great. The issue is where you've put the file.
.htaccess files are meant to be in the root folder and sub-directories of your website, not in the config files for Apache. Think of them as configuration files the server will find on-the-fly as it serves up documents, not static configurations loaded when the server starts (which are found in the "conf" folder you referred to). (See https://httpd.apache.org/docs/current/howto/htaccess.html)
For WAMP, the root folder is typically a folder called "www" and is normally located at c:/wamp/www. See Where is the web server root directory in WAMP? More commonly, though, this folder is called "public_html" (such as with LAMP, XAMP, MAMP, or default Apache installs).
