There is no doubt the search industry has evolved. Just one look at how search engine results pages are currently laid out shows how things have changed. We have come a long way from 10 blue links. But have we gone far enough? At SXSW earlier this month, information access was a hot topic.

If you want to improve your Google searches you can find many useful queries on internet and, if have time, you can also attend a specific Google free course.
But just few people know that there are specific queries available for Gmail.
I found some of them casually when I need to search some specific, old emails into my accounts some days ago. Then I discovered that Google itself published a complete list of all the possible queries accepted by Gmail.
I warmly suggest you to spend some minutes reading and exploring all the queries because they are really useful when you use Gmail in a professional way.
Here, I just want to sum-up some of them that, in my experience, are the most common you can use when you are becoming crazy looking for a specific email you sent or received.
The powerful feature is represented by the possibility to mix the different queries to create super-queries that can intercept the “wanted” email or documents in a less than a second.
Time
after:2010/10/24 before:2011/09/24
Here you are defining the time range and Gmail will show all the emails sent or received between the two specified dates.
From or To
from xyz@zyw.com to:xyz@zyw.com
Where xyz @zyw.com is the email address you are focusing on.
from:tom OR from:Luis from:tom OR from:Luis -meeting
In this case you are looking for an email from Tom or (plus) Luis but it hasn’t to contain (- minus) the word “meeting”.
Bcc or CC
bcc:xyz@zyw.com cc:xyz@zyw.com
Where xyz @zyw are specific email addresses you are looking for.
Filename
filename:invitation filename:(jpg OR jpeg OR png) filename:(doc OR docx OR pdf) filename:invitation(doc OR docx OR pdf)
Subject
subject:meeting
Attachment
has:attachment
Spam
in:spam
And you check into a specific folder. In my case: the Spam folder
Larger or Smaller
larger:25MB smaller:250MB
Some complex query examples:
from:xyz@zyw.com filename:(jpg OR jpeg OR png) to:xyz@zyw.com filename:(doc OR docx OR pdf) from:xyz@zyw.com filename:invitationfrom xyz@zyw.com to:xyz@zyw.com filename:(doc OR docx OR pdf) subject:meeting after:2011/10/24 before:2011/11/24 in:spam subject:meeting
Hay veces que queremos instalar alguna aplicación y no sabemos muy bien cuales son los repositorios correctos PPA de Launchpad. gracias a PPASearch esto se hace todo muy muy fácil. Lo primero que hay que hacer es instalar esta aplicación en nuestra Distro con los siguientes comandos:
sudo add-apt-repository ppa:wrinkliez/ppasearch
sudo apt-get update && sudo apt-get install ppasearch
Cuando ya tengamos instalada esta aplicación, podemos buscar el repositorio que mas nos interese, para hacer eso lo único será ejecutar PPASearch y el nombre del programa de lo cual buscamos el repositorio: ejemplo
ppasearch skype
Buscando por los repositorios de Skype me salieron diferentes repositorios y cada uno identificado con un numero, para instalar alguno de ellos, lo único será elegir el numero correspondiente y PPASearch se ocupará de instalar el repositorio seleccionado. ¡Muy buena herramienta!
Agradezco mucho el Blog Ubuntulife por su labor y por todas las informaciones y ayuda incluida esa entrada http://ubuntulife.wordpress.com/ 
Today in our Linux Page (in Spanish) we have posted a brief review about http://appnr.com/ an online resource page where it is possible to find a huge amount of programs ready to be installed. In few words it is possible to directly install them with just a click on the the download button on the right of the page. To take advantage of this feature please, check (once a time) to have apt url installed. If you have not apt url on your PC you can install it by terminal with sudo apt-get install apturl. Moreover the appnr.com website is very easy to explore with a very intuitive graphical menu on the left side of the screen and a powerful internal search engine. Appnr.com also contains a very practical search option which allows you to find the programs already separated between Gnome, KDE and XFCE. To sum up it is possible to affirm that appnr.com could be very useful especially when we don’t find .deb packages and don’t want to spend time manually installing programs. Anyway, to keep always my Ubuntu updated, I personally prefer to directly add repositories in Third Party Software (in System – Software Sources). Something to try!
