Similar Thread function?

[mobosix]

How does vB determine which threads are added to the bottom of other threads via the Automatic Similar Thread Search function?

Thanks,

Keith

You can read the code used in includes/functions_search.php - the functions fetch_similar_threads is around line 340. The method is different based on whether you are using fulltext search of vbulletin's search engine.

Lynne, I've looked through this code and while most of it makes no sense to me at all, but I'm interested in the piece of it:

// this is an arbitrary number but items less then 4 - 5 seem to be rather unrelated
if ($thread['score'] > 4)

If I increase that number, would it make the threads returned as similar be more relevant to the current thread?

Take a look at this mobo http://www.vbulletin.org/forum/showthread.php?t=201651

I installed it on my forum, it works very well.

That relates to this line in the query:

MATCH(thread.title) AGAINST ('$safetitle') AS score 

I'm not that familiar with that function, so I can't answer your question. I suppose you can play with it on a test site and see what happens.
