I have never had much luck trying to find a specific post, subject or even keywords using this search on the forums. Has anyone else experienced this?

I feel bad for newbies (like I was once) that try to find info- come up empty. My tip: use Google. It usually has recent results.

Google with " " and time filter can usually find a post if it exists.

For unknown reason, the search function here works better for me with Chrome than it does Explorer.

Never had any issues tbh.

You may want to check what's being searched. By default it is set to "This Topic". If you change that to "Forums" you should get better results.

Using as many filters as you can helps somewhat. You just have to recall all the relevant details.
