Re: How to delete lots of related keys at once

For instance, I'd like to cache my search pages, as they are really database/cpu intensive.  For instance, on a social networking site someone could be searching based on sex, height, religion, hobbies, location, and other combined criteria.  This sort of query hits the databse hard, and it wouldn't take too many of those to crash the db server.

 

In this case wouldn't it be great to cache every single search that comes in, so that in a duplicate search the app wouldn't have to hit the database again?
