If anyone wants a bit of easy practice using both the Search and the ‘onebox’ style of quoting you can have a play in the A-Z Sex Toys - Forum Topics game? 
To onebox a quote you simply paste a link on a line all by itself, like so:
https://lovehoneyforum.com/t/a-z-sex-toys-forum-topics/259174
And the forum will turn it into:
It works with all forum posts, as well as most websites (though unfortunately not Lovehoney’s).
And the Search is really easy. Pop your term in the box and click the magnifying glass. Order by relevance or latest, etc. And then for the game you’d long press/right click on the post header you wanted for your answer and ‘copy link address’, come back to the A-Z, and paste your link in the box as above.
