I don't really expect a complete answer, but just throwing this out there in case there are any php/sphider savants out there.
I was just wondering if it's possible to control the search string regardless of what people input (basically disable the front end search functionality unbeknownst to user). This would be for a joke type search. For example, someone searches for "windows 7 troubleshooting" and get results for some other random (embarrassing, funny, etc.) search term that I have predetermined.
It would be funny to have a couple hundred search terms that were randomly selected from a pool of choices whenever someone used the search. What do you think? Would this be a ton of programming/work, or something rather simple to someone who's got a little game?
