Beagle Ð The Search Tool. To get to the basic search tool on the GNOME Desktop environment, click Places, Search for Files. If it searched for files, you know it's the older Search for Files regime, which is essentially a front end to the Find Command. As such, you can search based on the name of a file in various folders, also known as directories using some of the characteristics of file such as the last the file was modified, its size, ownership and such similar characteristics. But Beagle is a very capable tool. It can help you search within the contents of not only text files but applications, PDFs and more. So let's see what we need to do to install Beagle. One way to do so is with the Add Remove Software Tool, which you can open with the System, Administration, Add Remove Software Command. Once it's open and I've already done a bit of steps in advance here, I type in Beagle, which searches for all packages with Beagle in its name and selected appropriate packages. The basic search infrastructure, back ends for various sorts of applications. So the indexing will include things like the contents of my emails within the evolution personal information manager. Once my selections are complete, I will click Apply and Fedora would download and install these packages. But that takes a while so I've already done this process on a different virtual machine and once that's complete, I can click Places, Search. Not search for files, search as in search for data on the Desktop. And that command opens this Desktop Search Window in which Beagle can help you look within various types of applications within these categories. And let's go over these categories. First, my files would be or would prompt for a search within User Home Directories, you being the user would thus within your home directories and their subdirectories. It can search within applications depending on what applications are installed at has appropriate plug-ins that work with Beagle. Beagle can search within binary documents such as those saved from office suites or even Adobe PDFs. It can help you search for pictures based on their names. It can help you organize your media; specifically your songs and videos. It can help index things like the contents of your source code files. The source code is the programming instructions. That's the stuff that's actually licensed as open source, thus the name. It allows you to search through the contents of archives. These are sometimes known as tarballs, typically with tar.gz or tar.vz2 extensions. As I suggested earlier, it can help search in things like emails and it's capable of searching through emails configured in Evolution, Thunderbird and even KDE's KMail. It supports searching through news suites, such as those associated with RSS. That's Really Simple Syndication, along with similar sorts of website feeds. Speaking of websites, the browsing history within browsers like Firefox or even Epiphany can be collected by Beagle. You can even search through your chat logs. Hey, that's important in some businesses since that becomes a record of say a conversation you had with your boss online. E-mail applications such as Evolution and Thunderbird include address books and Beagle can search through those as well. Of course, it can search through local note applications such as Tomboy and KNote, along with events that you've scheduled. Evolution, as a Personal Information Manager, includes a scheduling tool and Beagle can search through those events. But with so many categories, the indexing process for Beagle can take hours. So you may want to regulate when Beagle does its searching and to do so you click System, Preferences, where is it? Search and Indexing and that should open the Search and Indexing or Search Preferences Window, which allows you to regulate when Beagle does its searching through all these files. If you're on a laptop, you may now want it to perform all these high disk-intensive applications, which could easily drain your battery power. You could set up what it indexes, adding more directories to what is to indexed. You can specify different applications as data sources and scroll through this. This gives you an excellent feel for the types of applications that Beagle can handle. Network Options goes even further. It can help you support network-based indexing. Gee whiz; imagine being able to search these types of files on remote systems. OK. These are the basics of Beagle as a Linux search tool.
