Hi, I sent you a ticket some days before and i didnt get any answer and also i cannot find the submited ticket. BTW i try to customise the plugin and looks not work corectly.
1. clicking in the settings you will see the setings looks stange and above the bar
2. when you try to search only after the 3rd character start searching but the post important is that the results showing overwrite the existing content and the search button if you click not working
1. The settings look fine on my end. Did you solve the problem? Or did it disappear?
2. You can change that behavior on the General Options -> Behavior panel: http://i.imgur.com/PHoRuA4.png
Both the triggering (character count) and the redirection & override. Override will only work if your theme default search does not have a different override enabled already.
The items on the page you linked (http://fuelsandlubes.com/flcc/) appear to be listings, which I guess is a custom post type? Have you enabled search in that custom post type? More information here: https://goo.gl/7KbZwj
