Assuming you just want search for your users and you're not concerned about how it works Google may well do the job well enough. As long as everything you want to be searchable is public (not password protected) it works pretty well and only takes a few minutes to set up and embed in your site/app. imo, go down this route if search isn't a core concern. Better to spend your time on whatever is core rather than tweaking with your search if that is peripheral.
