Glad someone posted this finally!
This is an ongoing problem, I have been experiencing it for the last couple of months. Last time though somehow I managed to search... I remember the error message came up but I just kept clicking here and there and made it work eventually.
Cannot do it now!!!!!
Hope the site owners / operators will read this.

It is so sad that the search function does not work. I used to visit this site often to search for recipes, but now it is impossible to find them. The search function hasn't worked in the past six months. What happened to the website owners?
