Google Raises Word Limit 71

Posted by timothy from the 32-is-nearly-the-answer-to-everything dept.
Philipp Lenssen writes "Google quietly raised their web search limit to 32 words. Previously, only up to 10 words were allowed per query, with succeeding words being ignored. This is not only important to specific approaches of advanced searching (for example, when you need to exclude many different keywords using the minus operator), but it's also of great help to certain tools using the Google API. While there doesn't seem to be any official statement from Google yet, some more details can be found at my Google blog."

    Now you can search for quotes, without having to strip half of the words away. Just cut and paste it in to the browser. I guess this will also make it easier to search for source-code, as it is now you will likely end up at a documentation - site. When you want is some sourcefile from some Sourceforge project.

      The "*" character, used as a wildcard in Google, doesn't count as a word. So even previously, you could search for quotes and replace certain words with * to fit the entire thing.

    32 word searching increases the complexity of the search many times over. For a ten word search you're usually talking about finding all documents with all ten words, ordering them by how many of the searched terms were found, and then by their linked-to values. With 32 you're finding ~3.2x as many documents, comparing for 3.2x as many words in each documents, and then finding how popular they were.

    So, um, wow.

      How are you finding 3.2x as many documents? You should be finding fewer documents, not more.
      • Does google limit search results to documents that contain every single word you've queried for? ...

        Oh. I see. In that case the complexity only increases with the number of times the document is passed over for each word, or 3.2x which is probably over twice as high as the average number of times a document needs to be scanned for a word before finding that it doesn't contain a word...

        That's not too hard. Why is there a limit?
      • Yes, you do find fewer documents, but you have many more potential documents. That is, when a search is run, you must find the documents that contain all of the keywords (in most search engines, anyway).

        So say you have search terms a, b, and c. The documents that contain these are found using the index that they construct, and the documents that contain a are set A, the documents that contain b are set B, and the documents that contain c are set C. You must then find the intersection of A, B, and C. A

    I discovered how to make a Firefox plugin for limiting Google searches [moskalyuk.com] to select few sites, but the problem before was that each site:domainname.com directive was treated as a term. So if you wanted to search 7 sites at once, then google would let you enter maximum of 3 keywords to span that search across multiple sites. So this keywords increase, you can do stuff like 5-word searches across 10 domain names, for example.

      though.. it's still not good enough.

      what I would hope for them to introduce would be a word blacklist that would be personal, and that you could include at least a thousand terms in it.

      why? TO AVOID THOSE FUCKING LINKFARMS, they usually have the same advert links in them so just adding the referral id of the owner of a certain farm will get a lot of meaningless sites out of the search. it's doable now if you make your own program that does the filtering(using googleapi. there's two ways, either go to the sites yourself or request the cache from google.. massive traffic in any case for you and the search will take ages to complete).
      • A personal blacklist is a pretty good idea. Google is already working on personalized search [google.com] based on a profile which contains a list of interests. They should try out more personalization like that.

        However, I don't think that's a good solution for getting rid of link farms. Google should deal with those itself because they mess things up for everybody. They should keep tweaking their alogirthms to detect link farms better and encourage people to report them [google.com].

  • The problem with getting good search results are synonyms (different words that mean the same thing) and homonyms (the same word that means different things). With the 32 word limit, you can avoid both of these problems by following a few simple steps- Let's say, for instance, that you live in new york city and are looking for a moving company that specializes in fragile antiques... typically, the vagueness of such a query makes it hard to find good results, but not if you follow these steps:

    1. Break your search into 2-4 principal, independent concepts- In my example, the concepts are NYC (the location) moving company (the company type) and antiques (the specialty)

    2. For each concept, come up with as many terms as you can that are descriptions or examples of the concept that are very specific and won't trigger homonyms- For instance, you wouldn't want to use the word "New York" because it is too vague and could refer to the state (a company in Albany, NY won't help you). However, "NYC" "Long Island" "Brooklyn" "Queens" "New York City" are great, even if they seem overly specific- You just need one of them to cause a hit on a relevant page.

    3. Put parenthesis around the terms for each concept (be sure to put quotes around each compound term) and OR together the items inside parentheses.

    This is what the entire search might look like:

    ("NYC" OR "Long Island" OR "Brooklyn" OR "Queens" OR "Manhattan" OR "Bronx" OR "New York City" OR "Big Apple") ("moving company" OR "moving companies" OR "specialy movers" OR "professional movers" OR "u-haul" OR "apartment movers") ("fragile" OR "antiques" OR "china" OR "difficult to move")

    It takes a bit of time to put together (and google will run slooooow because this kind of logic is very difficult for the search engine), but a search like this will give you the best possible results on hard queries.

      Classic newbie mistake. The biggest problem with search engines is that they return too many answers not too few. Adding regular expressions or stemming makes your answer set even bigger.

      What we need is ways to make the answer set smaller, not larger. Hence the benefit of clustering, for example (see for example http://vivisimo.com/search?query=search+trees&v%3 A sources=Web [vivisimo.com]).

        The problem that annoys you is not the size of the answer set, but the lack of a proper sorting function (by relevance) to satisfy you. The fact that you find your desired answer at the 10th or the 30th position is a sign that sorting doesn't work like you'd expect it to. It has nothing to do with the size of the answer set.

                  Easy: if an operation is sufficiently expensive, the actual cost is noticeable, even when rare. This is known as heavy tail meaning that "a relatively small number of very high cost events skews a mean calculation".

    "it's also of great help to certain tools using the Google API"

    Hardly. The Google API is limited to 1000 searches per day, making it useless for any sort of web application. About the only thing I can think of that it would be useful for is a desktop program in which the user would only perform a limited number of searches.
    • A java/flash, etc. applet would work, wouldn't it? Or do they limit the daily use with some sort of developer account embedded in the code?
      • It's a developer account. So each search each user did would contribute towards your total.
        • The solution is obvious. You set up a web app and get your visitors to sign up for a Google API account and copy the details in to a profile. They log in, do their searches, it deducts from their own totals and the web app just plods merrily onward.

    • Hardly. The Google API is limited to 1000 searches per day, making it useless for any sort of web application.

      Well, it appears to be useless for your web application. In my opinion, 1,000 queires a day seem a lot for a non-commercial product. Google may add a commercial program that allows more than 1000 queries per day: (google answer: http://www.google.com/apis/api_faq.html#gen15 [google.com].

      Lastly, I always like to mention the API is a new, free, and beta service. My gut says that if you need more than 1,000

      • That doesn't make any sense. Are you saying that a non-profit web app couldn't attract more than 300 to 500 users per day? That's nothing.

        • Are you saying that a non-profit web app couldn't attract more than 300 to 500 users per day? That's nothing.

          Sure it could, and if all the web app did was search, the the 300 to 500 users (or more) would exceed the 1,000 queries per day. On the other hand, if all the web app did was search, why would Google want you to freely take people away from their search engine?

          IMO, this API could be put to a good, supplemental use in an application (one where searching could happen, but is not the primary focus).

          • Even with an application, you'd be artificially limiting the possible growth. It wouldn't take very many users before you'd have to remove any such feature from the application because you'd have hit your 1000 search cap.

            And who said anything about taking people away from google freely? The problem is they don't allow you to purchase more searches.
    • Hardly. The Google API is limited to 1000 searches per day, making it useless for any sort of web application.
