Hi Jeremy,
That unfortunately is beyond the plugins capabilities. The search uses the local database to search for content, not the actual visible content. Therefore it is not possible to index 3rd party sites, I’m sorry.
It depends on how do you want to style the autocomplete. It is a secondary input, that is absolutely positioned just above the search input field, so it hovers under it. Basically the search an the autocomplete are on top of each other. The autocomplete input field can be accessed with custom CSS rules like so:
[html].proinput input.autocomplete {
color: red !important;
}[/html]
This sample code will change the color of the text to red.
