Best newsgroup search engine?

[Happy Hopping]

I have some problem w/ binsearch.info, some times it can find the listing, some other time, no. In fact, w/i the same session, 1 search show such and such item is on whatever newsgroup, and another search shows nothing.

Can someone recommend some good newsgroup search engine? I prefer a search engine that keep 90 days of thread subject.

I fail to see what this has to do with Networking & Security.
