    2. Copyright law provides for “fair use” of portions of a copyrighted work. You can copy no more than a SINGLE paragraph from the article to your post (3 or 4 sentences at most).

    3. You must provide a link to the article along with the name of website. For example: ww.xxx.yyy/zzz (The Lower Thumbsuck Daily News).

    4. You must provide, in your own words, a brief summary of the article AND your reasons for believing it will be of interest to TFL members. Failure to do so may result in the thread being closed or your post being deleted as a “cut and paste drive by.”

    5. Photographs and other images are also copyrighted. "Hotlinking" of images (so that it appears in your message) from other sites is also prohibited unless you own rights to the image. If you wish to share an image, provide a clickable link to it.

    Posts that do not follow these new guidelines will be altered or deleted by staff. Members who continue to violate this policy may lose their posting privileges at TFL.

Searching TFL "Gun Show" with abbreviations...NOT!

I used to search the For Sale forums with the abbreviation DFW to find guns being sold in my area. For some reason, that quit working awhile back...

Is that a bug or a feature? :D
 
There are a few common words that are excluded from the search index. It is likely that 'DFW' is one of them. I don't get a single hit when I search any of the forums for that term. This limitation is in place to keep from bogging down the search engine when members search for words like, like, the, very, for, from, etc.

Try searching for the term 'Dallas', 'Worth' or 'Texas' instead.

Hope this helps. :)

P.S. It's a 'feechur', not a bug. ;)
 
Dave, I thought that might be the answer, but I checked the common word list and DFW isn't on it (and it shouldn't be). So I guess it's a bug of some sort.
 
I wonder if the minimum allowable letters in search terms has been bumped up past three...
Try searching for the term 'Dallas', 'Worth' or 'Texas' instead.
The problem is that few people put "Dallas" in their posts or spell out the state names.

Dunno what the deal is, but this was working as recently as a week or so ago...
 
I've heard of a program that makes that list dynamic rather than static. Once a word is found in the database XX,000 times, it is ignored by the search engine. Again, the reason is to speed searching.

Tyme may be able to answer whether or not we are using such an animal.
 
About the time the search engine began working again (yay Tyme!), I quit being able to find my username in other people's posts. I can still find my own posts, but can no longer glance around and see if anyone's invoked my name lately. Figured either I've posted too many times here, or my name's too short. :confused: Annoying, but I guess it's not really the end of the world.

Yep. And I can't lengthen it with an asterisk, as I sometimes do on other boards.

I double checked and the word length allowed is still 3 characters.

I compared all of the search parameters at THR with those here at TFL - they are the same. Searching on "DFW" at THR returns lots of threads. So that tells me DFW (and "pax", etc.) aren't indexed here for some reason.

There's not much else we can do except wait for tyme to take a look into why this is happening, or rather not happening.
 
Very strange. Both "dfw" and "pax" are indexed (818 and 3425 occurrences, respectively), but vbulletin isn't showing those results for some reason. I'll look into it, but maybe not today. I did tweak the searching a bit back when I re-enabled it, but only to reduce problems caused by apostrophes and such. Maybe I broke something.
 
I have now.

This new search system looks good. I pray to the Gods that I'll never have to deal with searching slowdowns again.

Guests are allowed to search.

Searches can now be 5 seconds apart instead of 10 seconds (and it's set at 5 seconds only to discourage bots which may decide to try flooding the search system).

The search result limit has been raised from 400 to about 15k.

Three letter words are now searchable. I'm not keen on including 2-letter words, though, so HK and 2-digit calibers may remain unsearchable. I'll probably try it out soon, though, and if the search index doesn't explode we can stick with a 2-char limit permanently.
 
Excellent job!!!

Are you using an SQL db other than MySQL to accomplish all that?

I did a quick check using "DFW" as originally reported here. A search over the last month using "Search Entire Posts" returned a usable and believable number of hits. However, changing only to "Search Titles Only" gave hundreds of hits. Looks like that one change caused the "Find Posts From - A month ago" to be ignored. Not a big deal, but it would be wasting cycles that don't need to be wasted.
 
It's completely separate from MySQL now.

Yeah, there are some caveats. Some of the sorting modes don't work, and apparently the date ranges don't work when searching thread titles. We'll see. There's no reason why date ranges can't work for title searches, it's just not working yet.
