The New American Standard version is a Protestant Bible. I think you are confusing the New American Bible with that one. The NAB is the Catholic one and the NASV is Protestant. That is why I prefer NOT to go to that website, because all of those versions are Protestant.
As far as for searching I like the English Standard Version website. The ESV is also a Protestant bible. Of course it does not have the 7 books that Luther tore out but I still like the search engine on that website. And many of the verses are much like the RSV-CE bible which of course, is Catholic. I like to search on the ESV website and then go to my Catholic bible. OR better yet I love the Douay-Rheims version and therefore I like the DR-V website; by the way, I’m so glad the website is back!!
