I’ve just found out that the Content Overview (Beta) search algorithm doesn’t consider replies in its results, just titles and content.
Feature suggestion is that it reviews all mentions of the keywords searched for.
In the meantime, what is the best way to identify topics (best answers, comments included) with any keyword, for example if it all needs updating? We have our email address featured in lots and lots of best answers, and I’m looking for the most efficient way to find and update this topics.
