Searching this way behaves the same way as searching using the text box always at the top of this [[agora]].
As of [[2021-02-27]], you can also just use [[open search]] to add the [[agora]] as a search engine; this works at least on [[firefox]]. You should be able to see the agora as an available search engine to add in the search box.
The [[agora]] will try to serve any relevant nodes for your queries -- useful for when you have notes on the topic you're searching for.
In every case, the [[agora]] will try to make it easy for you to 'click through' and continue your search elsewhere -- in established search engines or the websites of your choice.
