I've always assumed that searching episode bodies for a string would also search the episode options, but it appears that it does not. The second option of episode 99782 of the Never Ending Quest contains the word "Analects". I searched for "analect" to see if the word had appeared previously, but there were no matches, not even for episode 99782.
I should therefore like the ability to search options, either incorporated in the episode body search or as an additional category of search.
You are correct, the current search functionality does not allow a user to search within the episode options. I've been thinking about it for a bit and I believe it isn't too hard to implement, either as a separate search, or included with the episode body search. I'm leaning towards including the episode options as part of the episode body search. Do you have a preference?
My own preference is the same as yours/
