If you don't have $80,000 to buy Google's solution then the chances are very good you don't have the money to develop it either. So the question becomes, can you live with what you can build?

First off, you want to be able to "translate some pages". That's a pretty tall order. Are you at least planning to buy this piece or are you going to build this too?

Second, you need to get a clearer idea of how good the search results need to be. Google has the best algorithms in the business and they aren't publishing them! People have a pretty good idea how they do it but replicating it will take a lot of hard work and more than a few braniacs in the barn. I recommend you look at Glimpse to see what some really smart people have been able to do with quite a lot of time. Google it ain't, but it's not bad either. Maybe you can use it as a backend component the way I did.

Unfortunately the search engine I built went straight to /dev/null along with the company that paid for it. They never sold a single copy to my knowledge. Wasn't the 90s fun?
