Google's Custom Search Engines (CSE) have been around a long time. I have personally been using it for a few years with no problems. It has helped boost the revenue for several of my sites by improving usability. Search Engine Roundtable ( [seroundtable.com...] ) has also been using it for a long time. If you want to be overly cautious or even paranoid just don't use it.
