In my last article we looked at some of the common Google search queries including, site:, inurl:, “brackets”, include (+), exclude (-), and the wildcard (*). You can also read my article on using Google operators for SEO.

There are roughly 50 or 60 other operators I know of that can use on various Google pages like News, Groups,  Maps, Books etc, but I’m just going to cover the ones that I feel are useful and personally use on a day to day basis.

Filetype:pdf
File type lets you search for particular documents. The most notable would be pdf, doc & docx (2007+ word documents), and xls & xlsx (excel spreadhsheets), but you can search for any file type.

This also works on web documents, so you can search for php, html, htm, js, css, asp, cfm (ColdFusion Markup Language), jsp (Java via JavaServer Pages), ssjs (Server Side Javascript), pl (perl), smx, py (Python), rb (Ruby), lasso (Lasso), dna or tpl (WebDNA).

Lastly, and what I find is most useful, is the ability to search for file times on Google image search. I generally want png’s because they are more likely to have transpaent backgrounds, so I always put a filetype:png on my searches. Note: Remember not to include the dot (.) of the filetype, this will not work: filetype:.png.

#..# Two dots between two numbers lets you specify between a certain range. For example: best books 2007..2009.

keyword ~glossary
The tilda (~) followed by glossary enables you to search for a particular keywords glossaries, doctionary meaning, list of terms, terminorlogy etc. For example: farm ~glossary

define:keyword
Using the define search looks for definitions of the particular word  or phrase, for example: define:calculator.

Google Calculator
I often use Google as my own personal calculator.  Here is a list of the operators you can use.

Specialised Information Queries

Below is a table of alternative search queries that may come in handy. Note this isn’t a complete list, but after looking through all the listed search queries a lot of them have become necessary because of Google innovations:

  • book (or books). Search for full-text books. book The Walking Dead.
  • define, what is, what are. Show a definition for a word or a phrase, this works similarly to the define: query explained above, but there is no need for a colon (:). define calculator.
  • stocks:keyword. This lets you see current stock prices using stock syntax, stocks:erts (Electronic Arts Inc).
  • weather keyword. Search for weather results for a city or suburb. weather brisbane.
  • cache:website. View the current Google cached version of a website. cache:http://kintek.com.au/web-design
  • related:website. See websites that are similar or related to the specified website. related:http://kintek.com.au/
  • info:website. This will give you a listing of terms Google can show you about yourwebsite, much of these have already been discussed. info:http://kintek.com.au

That’s all from me. This isn’t a complete list of all the Google search operators, but in all seriousness I don’t think you would ever need to use terms like intitle:keyword and allinanchor:keyword.
