I’m starting a new tag with this article—Technical—where I’ll cover technical subjects with little or no explanation of the jargon. These topics are not intended for the novice or the uninitiated. Everyone’s free to read and participate in the discussion, of course, but sometimes I feel like getting to the heart of the matter more than I feel like setting up the discussion.
Chris Ilias quoted Giganews support on why XPAT isn’t supported on Giganews servers:
The XPAT command attempts to search through our entire spool of over 700 million articles, to match on a specific keyword, that is often found only in a handful of newsgroups. The command puts enough of a load on our servers, that several people using this at one time can affect the performance that all of our customers receive.
As one of the posters in that blog pointed out, this is somewhat misleading. XPAT only searches one group; a GROUP command must preceed an XPAT command. That reduces the number of articles being searched by a great deal. But what if it could be reduced further still?
