Just wanted to paste an update based on BB-Forrest's comments in the IRC chat:
<oeuftete> BB-Charles, BB-Forrest: once you get the new supporter feature stable... um, could you fix the last one? Saved TL search has never worked even slightly
<BB-Forrest> oeufette.. that's not true
<BB-Forrest> "even slightly"
<BB-Forrest> is totally offbase
<oeuftete> BB-Forrest: it works 0% for me
<BB-Forrest> yes, it has one small bug we should fix
<BB-Forrest> about the display terms not matching up.. or some off by one error somewhere i need to solve
<BB-Forrest> but don't exagerate like that
<BB-Forrest> its annoying
<oeuftete> I can't speak for everyone. It does not work for me. At all. I have never got a player shown who resembles at all my saved search. And the search itself can't be saved reliably.
I'm dismayed by this response. Being completely honest, it has never worked for me, and it's clear that other posters in this thread have the same problem.
I just played around with it some more. It appears to work iff I specify all four skills. If I leave any blank, then I just get an apparent default result (I'd guess it's the player with the highest actual bid that's <= what I can afford). That's more than one small bug.
This also looks like a symptom I see over and over in BB, whether it's in the handling of TL forms, the parsing of BB forum markup, the display of skill levels... it looks like there's a different implementation in every different place, instead of the use of one piece of library code. So bugs happen more frequently.
Finally, I've spent a lot of time giving free quality testing and bug reports to BB over the years. This is the last.
