from others?
both
I heard its a new beta engine that one of the things it does is
remembers successful searches of groups of words that the users made
and once you search one of the words again it proposes the others:
Example:
1) Search words: apple fruit banana
2) Click on any of the urls found
3) Go back to kuchita and search for apple and you will see that if
proposes fruit and banana as alternative searches.
I tried it it works, I imagine that if it gets massified it will be
extremely useful.
