There is a site for etymology: http://www.etymonline.com/
He gives the result: selective 1722, from about. recherché "carefully tracked down" pp. rechercher "to search." Commonly used 19c. food, styles, etc., to indicate implicit superiority.
I don’t know if they got the API, but they use the script for their request.
So, find a good way to discover "oh." in the above sentence.
Cheers, Erik
