Google search URLs revealed or How to create your own search URL

Tuesday, January 30th, 2007

We all know the Google Advanced Search page that lets you refine your searches and find what you need faster. But how many of us understand the complicated URLs the search engines generates?

Well I am not saying that I’m some sort of expert but here are some information regarding the URLs generated by Google. Let’s start by looking at one such URL:

http://www.google.com/search?as_q=nintendo+wii&hl=ro&num=10&btnG=C%C4%83utare+Google&
as_epq=&as_oq=&as_eq=&lr=&as_ft=i&as_filetype=&as_qdr=all&as_occt=any&as_dt=i&as_sitesearch=

You don’t understand much and it looks quite long but it doesn’t have to be this way. Many of the variables included are not even used in the query. Here are the basics:

What you should know is that you always start with: http://www.google.com/search?. This tells Google it’s an advanced search and that there are some variables to come. Besides, remember that all the variables must be connected with ampersands (&; ex. as_q=nintendo+wii&hl=ro) and if you want to use more than one search terms just use ‘+’ (ex. nintendo+wii) between them. Speaking of variables here are the most important tags you can use:


as_oq -> This tells Google to find pages in which at least instance of nintendo OR wii is found
as_q -> This means that you look for nintendo and wii in the same page
as_epq -> Google translates this as a Google search of “nintendo wii”, searches the exact phrase ‘nintendo wii’
num -> The number of results you want displayed, it ranges from 0 to 100. If you set num to 0 you will get the ‘No match found” message
safe -> If you set this to active the Google Safe Search is on and the adult material will be filtered
as_eq -> Use this to exclude a term from your search
as_qdr -> Shows only results that have been updated in the given time interval. Possible values: y (year), m6 (6 months), m3 (3 months).
as_sitesearch -> Limits the search to a specific domain or TLD (.us; .gov; .co.uk; .ro; etc)
as_occt -> This is set by default to ‘any’ but if you change it you can search in: title, url, links

The goal of this article is not exactly for you to use from now on hand-made search URLs but yo better understand how the Google search engine works and if you please to create some URLs for yourself.

Pro guide to Google searches. Part II

As I was telling you in the first part of this article, I am glad that we’ve got over the basics of Google searching so now we can look into more interesting search options.

First of all there is a part of Google’s syntax that allows you to tell it where exactly to search. This comes in handy when you know part of a URL or maybe a title but you can’t find the exact page.

You can use ‘intitle:’ to search only the titles for web pages, as many of the other functions that are to follow ‘intitle:’ has a variation, namely ‘allintitle:’ that includes all the terms that follow in to the title search:

intitle:”Santa Maria” boat -> searches in title for Santa Maria and does a search on the term boat
allintitle:pirate ships treasure -> searches in title for all the terms

I think you’ve got the idea so here is a list of syntax words that work the same way:

‘intext:’ works the same way only restricts the search to the body of web pages, excluding URLs or titiles
‘inanchor:’ a anchor is the description for a text link: <a href=”http://our-picks.com”>Our-picks</a> here Our-Picks is the anchor.
‘site:’ here you can use bot hosting and domain;this works well with the main page of a site (ex: cars site:co.uk)
‘inurl:’ searches the URL for sites, including subdirectories, it is highly recommended that you remove the ‘http:’ prefix before the search
‘link:’ this one is interesting since it shows you the sites that point to a specific URL, any page of the site not only the main URL
‘cache:’ returns the page from Google’s cache as it looked the time, useful when you want to find something on a page that changes frequently
‘filetype:’ works great with other syntax elements when you need a particular file type, like ‘.pdf’ or ‘.doc’ etc. (ex: planes filetype:pdf)
‘related:’ returns a list of pages that Google considers are related to one another
‘info:’ returns links with more informations about a given page, works well only if the page was indexed by Google.

Pro guide to Google searches. Part I

We all use Google every day, quite a few times a day even and most of us are very pleased with it. But are the results to your searches always that relevant!? Often you find irrelevant results and it takes you longer than it should to find what you want. But is this because of Google’s faulty search algorithms or is it because sometimes our searches can be ambiguous?


Well whatever the case after the Gmail search article I decided to expand the subject a little. I know some things you will find here you already know and some of them might be new for you. Anyway you can consider them as a reminder of what searching on Google really means.

I will start with the basic syntax that I am sure all of you know, but it’s the basis for further more complex syntax. For example:

You can search whole phrases by using quotes like “Rose Chappel” instead of plain Rose Chappel. The first query searches for the Rose Chappel and the second searches for the words Rose and Chappel.

I presume you also know about word exclusion, when you want to exclude a certain term from your search: PS3 -price. This will exclude all the results that contain the word ‘price’. You can do this with phrases also: PS3 -“technical specifications”. Note that there must be no space between ‘-‘ and the word to exclude.

What you must know is that Google excludes by default some common terms like I, of, the, etc. If you ever need to make Google include a given term all you need to do is put a ‘+’ in front of it: +the tower. Note that, when words like these are included within a phrase search they are automatically included like: “the tower”.

Now lets talk about some more complex searches whit ‘AND’ & ‘OR’. By default Google includes all the terms in the search but you can specify that one word OR the other should be searched. To do this insert the capitalized OR in your queries: expensive (red OR green) dress. You can also replace the OR with “|” the so called ‘pipe’ symbol. Needless to say that you can use OR with exact phrase searches: “complete idiot”|”total idiot”.

Speaking of synonyms you can ask Google to search synonyms of a certain word you search by using the ‘~’ key. For example: ~wood is going to search for both wood, woods, forest, etc.

Search Gmail geek-style

I know what you’ll say, that you can do all this stuff using the ‘Show search options’ button. But if you’re like me and you like doing things simple, quick and using your keyboard then these tips might just be useful.

We all know the search bar in our Gmail accounts that lets us keep track of the e-mails we sent and received over time. Also we all know the advanced menu that helps us find that important e-mail you’re looking for 30 minutes. If you combine the two mentioned above you get the following:

Here are some standard tags to find e-mails, their function can be easily deduced:
– from:
– to:
– subject:
– label:

All you have to do is type it in the search box like so:
from:co_worker@domain.com
or maybe
to:beloved_wife@gmail.com

Another interesting search criteria is ‘filename:’ after it you can add the name of a file attached to a e-mail and better yet you can put there only the extension and it will find all the files with the given extension.

A interesting combination is “in:” and “is:”. It tells Google where to look ( inbox, spam, anywhere but it does not work with the ‘sent’ folder) and is: has several values (starred, unread, read). You can use them separately or you can come up with expressions like:
in:inbox is:unread

There are also several searches I think you will find easy to understand:
before:date (yyyy/mm/dd)
after:date
cc:
bcc:

Now that you know this basic syntax you can evolve using combined searches like:
to:etherfast subject:(hardware OR playstation)
from:etherfast before:2006/01/23 subject:games “WoW” price

There you have it, the possibilities are practically infinite, that’s what I like about Google, it just provides the tools for you to enjoy.

World’s biggest computer

Reading all about the World’s smallest computer and wall mounted computers made me think how does the world’s biggest computer look like.

Well that’s one question I haven’t find a answer to just yet. It seems that the World’s biggest computer is not build just yet but the project was won by IBM in September 2006. We’re talking about the supercomputer project for Los Alamos National Laboratory. Roadrunner, as the supercomputer was nicknamed is meant to perform one petaflop ( that’s 1 quadrillion, for those not familiar with Star Wars like slang) calculations per second, and the U.S. Department of Energy’s National Nuclear Security Administration (NNSA) has disposed a sum of $35 million for the first phase of the project.

The idea behind Roadrunner is to combine 16,000 AMD Opteron processor cores and over 16,000 Cell processors special designed by IBM, Sony and Toshiba to perform physics calculations for the Play Station 3 gaming platform, all that mounted on System x3755 servers with four Opteron processors apiece and IBM BladeCenter H servers with Cell-based systems.They will run using Linux (choke on it Bill) to assign the tasks to be processed to the part of the system that’s ready to handle it, this means that basic tasks can be handled by the Opteron processors and the more complicated mathematical problems will be solved by the Cell processors.

There are several issues to discuss such as the estimated $10 million in operating expenses just for electricity, but by now the project is well underway and we can expect to see the finished behemoth sometimes in the near future, for now the US Government will settle with the smaller brother, the IBM Blue Gene/L, located in the sister laboratory of Lawrence Livermore National Laboratory. The Blue Gene can ‘only’ performs 280 trillion calculations per second, or 280 terraflops (for you to compare Roadrunner will be one quadruple times faster).

How to make the Robot dance

What do you need to remote-control one of those cool robots that you see nowadays in the shops?! Well you can use the remote that usually comes with them, or you can use your voice and a Wii remote!

All you need is a Robosapiens robot and the Robodance software. Here you can see a video of what the basic principle is, what you have to do is talk & use the Wii remote to control the movement of the robot. You can use drag and drop scripts and other interesting stuff given the fact that the Robodance software is open source and actually a SourceForge project. More insight you can get watching the video but I find it cool as a idea that you can control the little robot using your voice and the Wii controller that I happen to love!

Regarding that, there will be some interesting stuff regarding remote-controlled robots later on when you will see how you can keep an eye on your dog back home when you’re still at the office.

Gmail storage space stops growing

Tuesday, January 2nd, 2007

google-gmail-infinity.gif

As some of you might have noticed the storage space for Gmail stopped increasing since January 1st 2007. In April 2005 Google made the leap from 1G to 2G and the growth never stopped since then. As those who watch carefully stated the storage quota increased with about 0.33 MB a day ever since.

It’s said that the sudden stop occurred due to the omission of the code that increase the storage quota after 31 December 2006. This might be true for we know Google to be quite lavish with storage space but it remains to be seen how quick will the problem be solved and how much is the storage limit going to increase after all.
