Numinix site search (or any other site search)

Is anyone here using site search code that's stable, or can anyone comment on the Numinix site search add-on? It hasn't been updated in a very long time, so I'm a bit reluctant to take a chance on it. I need to index and provide a search facility for just part of the website. The Numinix add-on looks like it would do the job, but I've had problems with their add-ons before and I'd like to hear from anyone who's using it. Or anyone who can recommend something similar. I know it's based on the Sphider search code.

Why do you not want to use the built-in site search? Is there a specific issue you are having?

We're setting up a recipe section on the site, to promote the use of our spices. I only want to search that section. The product search could possibly be modified for that purpose but I don't have time to fool with it right now.
