I ask myself rhetorically and the Lab seriously, if there will ever be a real functional useful Search capacity in the Marketplace? Because right now it is borked. Yes, it'll find what you want but it will also bury those few items in a huge avalanche of completely irrelevant crap.
Example just now: I saw someone wearing a cute cropped T-shirt with the logo "No Bra Club" at a show, sent her an IM with compliment and request for the name of the maker, received back only silence. Fine, I thought, there's the Marketplace, I will just go look for it!
Typed in No Bra Club. 400 results. The first page has one (1) t-shirt with the phrase on it, the other articles are entirely different. Next page: one relevant result. Next page: not a single relevant result. Next pages: only irrelevant results.
So I read the Help page for the marketplace, and learned that boolean search operators are allowed. Great, let's try that. Typed in no AND bra AND club. 524 results! (Anyone that knows about search is already shaking their head, just at that number.) Choose one at random: https://marketplace.secondlife.com/p/INDIGO-VIBES-Lil-Black-Tank-YELL/20185345. Does the search phrase occur in the article? NO. How many of my individual keywords are in that article? NONE! ZERO!! Then why am I seeing it? Repeat that 500 times. I would personally call this a search failure.
It's about time that you fixed this, guys. Database searching is a problem that was fully solved forty years ago. This is not rocket science.
