Right. It should be easy to switch between isearch and query-replace.

"What" versus "how".

We have a search history because it's often the case that we want to 
repeat something we've recently done --- look up the same word, find the 
same function, and so on. It doesn't make sense to me that the exact 
mechanism we use to search for a particular thing should affect its 
recency or the way in which we recall it.

It's very easy already to casually switch between literal and regex 
isearch with M-r. Why should this distinction affect the way in which we 
recall that search?

Both.
