eBay actually has a pretty interesting search engine, but it's not boolean like most others.
Its general rules are that (except for delimiters like I get to below), if you throw a bunch of words in the search area, its default hash for the search words is "all" -- i.e., it won't pull up listings unless they have "all" the words in the subject.
The problem of course, and we've all seen it, is that you go looking for something, but you have trouble keeping all the crap auctions out of your search. A good example is if you're looking for a part for an SKS rifle.
Unfortunately "SKS" seems to be the abbreviation hobbiests use for "socks" of yarn, so you get this retarded listing consisting mostly of yarn auctions, with a set of parts or two in between.
So, what you've got to learn is to put mandatory, but alternative terms in a
+() and exclusionary terms in a
-() which is how eBay handles that.
For example: In the early 1980s, the Coleco games company manufactured these nifty table top games in little mini arcade cabinets. Unfortunately for the ebay searcher, Coleco also manufactured cabbabe patch dolls, they made the "Colecovision" game system, and they sold air hockey and footballs systems, and assorted other crap.
If you just search for
"Coleco" you'll be scrolling through page after page to find what you want among hundres of items you're not even remotely interested in. What a waste. Time is money, baby.
And, If you try to narrow the search to, for example, "Coleco Game" you'll have two problems. First, you will still get a lot of crap you're not looking for, including air hockey, the colecovision stuff, etc. But you will also MISS auctions in which someone described the item as "Coleco handheld Pacman" without using the word game. DOH!
So, to do it right, you would use something like this:
coleco +(table, handheld, hand, frogger, galaxian, pacman, zaxxon, donkey) -(controllers,colecovision, patch, cartridge, air,hockey,football)The first word: "coleco" is mandatory. Every listing must have it.
In addition, the parethesis with a "+" in front tells ebay at least one of the terms in paren must ALSO appear in the title of the auction. Note that these terms are comma separated. Also, if you want to use a two word phrase, i.e., "donkey kong" then you need to put it in quotes.
Finally, the things in the parenthesis with a "-" in front are things you want to exclude. You're telling ebay that even if your other rules are met, NO LISTING that has any of the terms in the "minus" brackets should come up.
In my example, you see that I search for Coleco. Then I use a bunch of terms, including specific games I knew they made in the "table top" versions, to focus on what I'm looking for. Finally, I get rid of came controllers, cartridges, cabbage patch dolls, air hockey, etc.)
Here's the result of that search:

(And yes, I've got a whole set of those old Coleco games from when I was a kid. They still work!)
