Its on my roadmap, I really want it as well, being able to link to search results is very important. EG:
Have you tried searching for “widgets” /search?term=widgets
I am also with @erlend_sh and @codinghorror here, that particular feature tends to trip me big time, I feel like a site has taken over my GUI without me giving it permission. I use search to move around the Internet not just a particular site.
This may be a user preference we can add later on.
