Search engine "search in results" besides Control-f?

[MilesAhead]

Is it just me or do none of the major search engines provide a "search in results" input box that only searchs the last results?  Seems like it should be easy but I can't seem to get there from here.

Try this one.
It has that ability.
Free too.

search example: word1 word2 word3
DuckDuckGo treats this as: word1 AND word2 AND word3
adding word4 would search within the results
not/negation for a word or phrase: -
or between a word or phrase: OR
phrase: ""
example: word1 word2 (word3 OR word4) -word5

I understand the use of operators but I still think there's greater utility if you have an input that only searches the results. It's not like it would break the bank to implement it.

It's funny because I ran into an old 2005 page comparing search engine features. Google was supposedly one of the few that had it.
