If I add the URL for a search to my favourites will it be dynamic?

In other words, will it re-do the search for the time it’s done?

In yet a different way of asking… If I did a search based on a keyword, then added the resulting URL to my favourites, then clicked on that item in favourites a month later what would I get?..

Exactly the same results?
Error?
A re-run of the search with newer threads included?

The results are actually a link with an expiration date, so if you try to access that URL past the time limit, it’ll let you know that it’s no longer valid.

So, to do the search I intend to do my only choice is to do it the conventional way?

That’s my understanding, unless there’s a way to form a URL to feed the search engine before it outputs the results.
