  News search function reactivated (was: News search function temporarily disabled)
 
The LUGNET News search function is now re-enabled. I completely revamped the index data structures and list-merge algorithm and rewrote the core query engine in C. It's a much more solid implementation. Everyone's patience during the outage is much (...) (24 years ago, 2-Jan-01, to lugnet.admin.general, lugnet.off-topic.geek, lugnet.announce) !! 
 
  Re: News search function reactivated (was: News search function temporarily disabled)
 
(...) Very good! Although the new search doesn't return most recent articles first like it used to. Is that how it should work? Now I can't see most recent posts that contain the keyword I want to search for, which makes the search pretty much (...) (24 years ago, 2-Jan-01, to lugnet.admin.general, lugnet.off-topic.geek)
 
  Re: News search function reactivated (was: News search function temporarily disabled)
 
(...) Could I suggest some amendments to the "To do someday" list (for an 'advanced search' only)? - Search by author - Search by subject line contents - Search by date range (or open-ended-- i.e. after date X or before date X) - Search for articles (...)

(...) Could you tell us the URL syntax for those of us willing to modify URLs? (24 years ago, 2-Jan-01, to lugnet.admin.general, lugnet.off-topic.geek)
 
  Re: News search function reactivated (was: News search function temporarily disabled)
 
(...) Not yet, no. See "to-do soon" section in previous post. (...) For now, if you don't mind URL mucking, you can manually append &qs=<number> to the URL and it will use that number (in seconds) as a time delta. For example, to limit posts to the (...)

  Re: News search function reactivated (was: News search function temporarily disabled)
 
(...) Sure! (...) These are mostly covered already due to the way the indexing works -- words closer to the beginning of a document are given higher weights than words occurring later in a document. When the indexer chews on a news article, it first (...) (24 years ago, 2-Jan-01, to lugnet.admin.general)
 
  Re: News search function reactivated (was: News search function temporarily disabled)
 
(...) Pretty much... actually, I was thinking more along the lines of an advanced search form though: Search for: ___...___ (uses +'s and -'s as is) Search for text in subject line [] (checkbox) Posted by: ___...___ (uses +'s and -'s... or no (...)

  Re: News search function reactivated (was: News search function temporarily disabled)
 
(...) One thing which would generally make it pretty easy to find URLs is to index "http". When dealing with special characters, definitely treat "/" and "\" as word separators. Probably ":" also. (24 years ago, 2-Jan-01, to lugnet.admin.general)
 
  Re: News search function reactivated (was: News search function temporarily disabled)
 
(...) Do you index the name in "X-real-life-name"? One thought, index the special strings "from:" and "subject:". The the search: from: ffilz Should rank my posts highly due to proximity. Of course it would be better to index the real life name as (...) (24 years ago, 2-Jan-01, to lugnet.admin.general)
 
  RE: News search function reactivated (was: News search function temporarily disabled)
 
(...) I think a multi-field advanced search is the way to go...much easier to use, IMO--something like the DejaNews power search: (URL) actual search keywords are in one field, and then there are numerouse ways to limit the search. --Bram Bram (...)

  Re: News search function reactivated (was: News search function temporarily disabled)
 
(...) Ya, let's see...as it assembles the text to index, first it grabs X-Real-Life-Name:, then it grabs either Original-From: or From:, then Subject:, then Keywords:, then Summary:, and then finally the non-quoted and non-sig parts of the body. So, (...) (24 years ago, 3-Jan-01, to lugnet.admin.general)
 
  Re: News search function reactivated (was: News search function temporarily disabled)
 
(...) Ya, something like that'd be good to slap on top after the base functionality. :-) Nobody wants to *have* to remember how all the squiggly and square brace thingums in a search box work. :-) (...) Ya, precisely. It was originally (summer of (...) (24 years ago, 3-Jan-01, to lugnet.admin.general)
 
  Article bit-flags (was: Re: News search function reactivated)

One thing I really really want is to be able to put messages into folders (if anyone knows of a decent newsreader which allows such - please let me know - it would be preferable that it do so without requiring me to store the (...)

  Re: News search function reactivated (was: News search function temporarily disabled)
 
(...) It works great! ... but the &qs doesn't carry over to the next page of results. So if I want to see more pages, I have to edit the querystring on each page. Since you already have the inner workings of this in place, it would be really easy to (...) (24 years ago, 3-Jan-01, to lugnet.admin.general, lugnet.off-topic.geek)

(...) oops, doy! I didn't put in the propagation of that URL term. I don't consider it 100% "documented" yet (it's still subject to change without notice), but I still shouldn't have missed that. Thanks. I'll fix that. The reason it's subject to (...) (24 years ago, 3-Jan-01, to lugnet.admin.general, lugnet.off-topic.geek)
 
  Re: News search function reactivated (was: News search function temporarily disabled)
 
(...) Wow! So you have terms for the ampersand options in a URL? My standpoint on this would be to put everything in a form and kill 2 birds with 1 stone - not having to think of how to name URL terms (unless you enjoy doing that) and having the (...)

  Re: News search function reactivated (was: News search function temporarily disabled)
 
(...) Ya, exactly -- first name the URL components carefully and then put a user- friendly level on top of it. Best of both worlds. (...) Ah, I see. Yeah, that could be helpful in certain cases, if you're scouring tons of results! I've needed to (...) (24 years ago, 3-Jan-01, to lugnet.admin.general, lugnet.off-topic.geek)

Of course it's stability depends greatly on your (...) (24 years ago, 3-Jan-01, to lugnet.off-topic.geek)
 
  Re: News search function reactivated (was: News search function temporarily disabled)
 
(...) I like Java. But this really needed to be close to the metal and generate code that would fit in the L1 cache for the non-memory-bus-bound portions of the loops. The GNU C compiler is incredible. (...) It's the best C code I've written in 12 (...) (24 years ago, 3-Jan-01, to lugnet.off-topic.geek)
 
  Re: News search function reactivated (was: News search function temporarily disabled)

(...) I probably couldn't, no, but a very experienced Java programmer and a good JVM machine could conceivably do better than C. (It's not unheard of for Java to be faster than C for certain types of things.) The big hits would probably be the JVM (...) (24 years ago, 3-Jan-01, to lugnet.off-topic.geek)
 
  Re: News search function reactivated (was: News search function temporarily disabled)
 
(...) Oh -- actually, what search engines typically do on queries (and I just finally added this last week) is downvalue relatively common words and upvalue relatively uncommon words -- what's called "term ranking" or "term weighting." For example, (...) (24 years ago, 4-Jan-01, to lugnet.admin.general)
 
  Re: News search function reactivated (was: News search function temporarily disabled)
 
(...) Todd, this would be really useful. I'll often search for a recent post, only remembering the poster's name and maybe one or two key-words, and that the post was in the past few days. I don't need two year old messages nearly as frequently. (...) (24 years ago, 5-Feb-01, to lugnet.admin.general)
