Control Fuzzy Searches


Choose when and how plurals and variations of your search terms are used in searches.

For the most part, eBay searches return only listings that match your search terms exactly. That is, if you search for possum, you won't necessarily retrieve the same results that you would in a search for opossum.

Historically, to perform a fuzzy search, you'd have to include all the variations of a word in the search box manually, like this:


(opossum,possum,apossoun)




To accommodate singular and plural variants of a word, you'd have to type something like this:


(antenna,antennas,antennae)




The OR search commanded by the use of parentheses  takes care of this nicely. But it's not always necessary.

All eBay searches automatically include common plurals and a few alternate spellings of words. For instance, a search for antenna will also yield results matching antennas rendering the use of an OR search or wildcards redundant in this case. The same is true for lens and lenses, as well as watch and watches. (The equivalency of plurals doesn't necessarily carry over to phrase searches. See "Use Keywords Effectively"  for an example.)

Plurals aren't the only variations included in fuzzy searches; search for spiderman and you'll also get listings that match spider-man. Likewise, t-shirt and tshirt are considered equivalent, as are Mr. T and Mr T.

Unfortunately, eBay's support for fuzzy searches is a little unreliable and difficult to predict; sometimes the results include plurals and sometimes they don't. While a search for tire yields the same results as a search for tires, the same is not true for tyre or tyres. Bad spellers will be sad to learn that paisly is not the same as paisley. And while eBay equates phone with phones, a telephone is still an entirely different animal.

Rather than relying on the whims of eBay's search engine, there's an easy way to test any particular variant. Just perform two searches: one for the singular version, and another for the plural (e.g., harmonica and harmonicas). Then, compare the number of items found; if they're the same, then eBay considers the two terms to be equivalent. (Since listings start and end all the time, the totals may change slightly; just repeat the search to confirm.) This tip is particularly useful if you're a seller trying to decide whether or not you need to include multiple variations of a term in your listing title .






The reason that eBay's fuzzy searches may seem inconsistent is that matches are based on a hand-selected dictionary of common variations and plurals, and eBay appears to be constantly revising these definitions. As the feature evolves, new matches may be added to the list while others proven to be troublesome may be removed. In an effort to keep fuzzy searches as unobtrusive as possible, though, extreme variants, such as "potato" and "tater" are unlikely to ever make the cut.

Search, Literally
Of course, the inclusion of fuzzy variations isn't always desirable. For instance, if you're looking for rooftop antennas for a Pennsylvania Railroad PA-1 locomotive (or a model of one), you wouldn't so much be interested in a book discussing the antennae of Pennsylvania cockroaches. To force eBay to search only for exact matches of words, enclose such terms in quotation marks, like this:


pennsylvania "antennas"




which is practically equivalent to:


pennsylvania antennas -antennae




Whether the quotes will be necessary, or whether you'll need to manually include variations (using parentheses), will depend on the particular search you're trying to perform.

Punctuation
To simplify searches that would otherwise require very cumbersome search phrases, nearly all forms of punctuation are considered equivalent to spaces in eBay searches. For instance, say you're looking for a 1:43-scale model car; you might expect to have to type the following:


car (1/43,1\43,1:43)




Instead, all you would need to type is:


car 1/43




where the 1/43 term will match "1 43", 1:43, 1;43, 1\43, 1-43, 1.43, 1!43, 1@43, 1#43, 1$43, 1%43, 1^43, 1&43, 1_43, 1=43, 1+43, and 1~43.

Now, say the aforementioned car is a 1968 Ford GT 40; the appropriate search phrase might then be:


(gt40,gt-40) 1/43




Here, the 1/43 catches all appropriate variants, but an OR search  is still required for both versions of the car name; although gt-40 is equivalent to "gt 40", it won't match gt40 (without any space or punctuation). This tactic is often necessary when searching for product model numbers, since most sellers aren't terribly diligent about dashes and other punctuation. For instance, if you're searching for the Sony XDP-4000X digital signal processor, you'll want to use something like this:


(xdp4000x,xdp-4000x)




Or, better yet:


(xdp4000x,xdp-4000x,xdp4000,xdp-4000)




since sellers frequently drop single letters that follow strings of numbers (like the trailing x here) for reasons that are not entirely clear. As you can imagine, eBay won't find these variants for you. Of course, you could also simplify the search with wildcards:


(xdp4000*,xdp-4000*)




Now, punctuation doesn't fall under the same rules as variations and plurals, meaning that you wouldn't be able to use quotation marks to restrict your search to include only desired variations, as discussed earlier in this hack. For instance, a search for:


"gt-40"




won't exclude variants gt/40 or gt:40. This means that the two terms in this search:


gt-40 -gt/40




will cancel each other out, and you'll always get "0 items found" as a result. Of course, if you're trying to curb your spending on model cars, this type of "search sabotage" might be just the thing you need to save yourself a few bucks.

Simplify your searches by making them a little more complicated.

Why should exhaustive searches be so…exhausting? Whether you're performing a quick one-time search or repeating the same search every other day, you can dramatically improve the efficiency of your searches and the relevance of your search results with some simple modifications to your queries.

You could fine-tune your searches by using the Advanced Search form, but this can be cumbersome and is mostly unnecessary due to the advanced search syntax.

Excluding Unwanted Results
Simply precede a search term with a minus sign (–) to eliminate any search results containing that term. For example, the query:


sunglasses -men's




will show all auctions containing "sunglasses" but not "men's", which should, at least in theory, show you a list of women's sunglasses. (Note that there's no space between the minus sign and the term "men's".) This approach is typically more effective than something like "women's sunglasses" because it will also include any auctions for gender-neutral sunglasses.

Naturally, you can exclude multiple terms, like this:


sunglasses -men's -children's -ugly




The scope of the excluded terms is the same as the scope of the search; that is, if you're searching only titles, the exclusions will apply only to titles. For example, the previous example may bring up some auctions with "ugly" in the description, provided the word doesn't appear in the title.

Exclusions open up a little paradox in eBay's search tool. In most cases, expanding a title-only search to include titles and descriptions will increase the number of search results. But when you exclude a word, a title-and-description search may return fewer results than the same search performed only on titles. Although this is caused by nothing more than the increased likelihood of finding one of the excluded terms when you search descriptions, it can still sometimes be surprising.






Be careful when excluding terms, especially when searching descriptions, because some sellers are sloppy with the words they include in their auctions. For instance, you might type:


digital camera -refurbished




to eliminate any refurbished (a.k.a. "factory reconditioned" or "factory renewed") cameras from your searches. But any listing that contains the phrase "Brand new; not refurbished" will also be excluded from your search. See the "Evolution of a Search" sidebar for additional examples.

Evolution of a Search
Adding exclusions to a search is typically an evolutionary process. Say you're searching for a plasma TV; you'd begin your search by typing:


plasma tv




which, not surprisingly, brings up some 2657 listings. About half of those are merely for plasma TV wall mounts, so you refine your search:


plasma tv -mount




But 1300 listings is still too many (how many TVs do you need, anyway?), so you further restrict your search by looking only for Panasonic TVs:


plasma tv -mount panasonic




But then it occurs to you that some inexperienced sellers may specify the brand only in the description, so you turn on the "Search title and description" option. Of course, this means that the -mount exclusion will also now catch phrases you might see like "wall mount available" so you take it out. It also occurs to you that some sellers may not include the term tv so you take that out, too. So you're left with:


plasma panasonic




which still results in more than 1300 listings. So, you turn off the "Search title and description" option and try again. Now, you're down to a little over 500 listings. It's at this point that you decide to visit the Panasonic website and figure out exactly which model TV you want. Then, you return to eBay and do a title-and-description search for only the model number (or rather, for several variations of the model number), which results in a very-manageable selection of only 11 listings. Watch that last one; it ends in 8 minutes!





Save Time and Typing with Wildcards
Place an asterisk (*) character in or after a search term to match all words that begin with that term. For example, the query:


phillips screwdriver*




will bring up auctions for "screwdriver" and "screwdrivers." An even better choice is:


phil* screwdriver*




which will catch the common misspelling "philips" as well.

As you might expect, if your wildcard searches are too general, you'll get a bunch of irrelevant results. A recent search for "phil* screwdriver*" brought up an auction for a Beatles recording because the auction description mentioned producer Phil Spector and a reference to John Lennon having made a joke about a screwdriver.






Since wildcards can also appear in the middle of keywords, you can further focus your search with the following:


phil*ips screwdriver*




You can also use wildcards with exclusions. For example, if you're looking for women's sunglasses, you might type:


sunglasses -men -men's -mens




to exclude results you don't want. But you could also use this much simpler version:


sunglasses -men*




to exclude all the variants of auctions for men's sunglasses.

Performing OR Searches
By default, every eBay search is an AND search, meaning that each auction must match each and every search term; the more terms you specify, the narrower your search becomes. But if you're looking for multiple items, or for an item that can be described in several different ways, you can combine your terms into a single OR search.

Terms in an OR search are encased in parentheses and separated with commas. Let's say you're looking for anything by the Beatles or the Bee Gees; you'd type:


(beatles,bee-gees,beegees)




Note the absence of spaces around the commas and parentheses. You can also combine OR and AND searches; if you're looking for any videos by the Beatles, you might type:


beatles (video,videos,dvd,dvds,vhs)




Or better yet:


beatles (video*,dvd*,vhs)




Note the inclusion of singular and plural variations of some of the terms, which may or may not be necessary; see "Control Fuzzy Searches"  .

Use an OR search to consolidate several searches into a single phrase. Say you're restoring an old Porsche 356b sports car; instead of conducting individual searches for each of the parts you're still missing, try something like:


(356,356b) (wiper,shift knob,hub cap)




and look for all the parts you need on a single page of search results. Plus, you can save your search or even get email updates  when new matching listings appear on eBay.






Looking for Phrases
Enclose phrases in quotation marks, like this:


"abbey road"




or, to look only for the CD:


"abbey road" cd




Note that the term "cd" isn't in the quotes, since it could be anywhere in the title or description. Naturally, phrase searches can be combined with exclusions, wildcards, and OR searches. Type:


"abbey road" -cd




to look for all listings except the CDs. Or, try:


("abbey road","white album") -cd




to include only these specific Beatles albums in your searches.

Want to see how valuable the quotation marks are in your searches? Try this:


abbey road -"abbey road"




This will show you all auctions with these two words, except when they appear together in the phrase "abbey road". When I tried this, the first auction that came up was a signed LP by Barry Manilow. Enough said.
