I like the usenet search engine Binsearch. But I had an issue the other day where a file name was posted onto usenet in a coded manner. I knew by using google the file was released 24th August 09 and google indicated it was posted to usenet at a certain time. Now binsearch searching did not come up with results so I had to manually go back in the newsgroup browse function to the date. In my case I found the file, going back to 24th August was no big deal, but what if the file had been posted 8-10 months ago. Is there a way of browsing a newsgroup with Binsearch or any other search engine restricting dates?
