-====== Packages - Search Packages ======
-Search for packages with "foo" in the name:
-<code bash>
-aptitude search foo
-</code>
-Search for **installed** packages with "foot" in the name:
-<code bash>
-aptitude search '~foo'
-</code>
-Search for packages from the section "foo" that are not installed:
-<code bash>
-aptitude search \!~i~sfoo
-</code>
-Pipelines allow complex searches:
-<code bash>
-aptitude search '~i' | grep -ie 'x11\|xorg' | less
-</code>
-Looking for packages installed from anything else than stable:
-<code bash>
-aptitude search '?narrow(?installed, !?archive(stable))'
-</code>
-Looking for packages installed from testing (assuming you have sources lists with stable and testing repositories):
-<code bash>
-aptitude search '?narrow(?installed, ?archive(testing) !?archive(stable))'
-</code>
-Shows all packages which are installed on your system because some other package recommends it, but they are not actually dependencies of packages:
-<code bash>
-aptitude search '?and( ?automatic(?reverse-recommends(?installed)), ?not(?automatic(?reverse-depends(?installed))) )'
-</code>
-can give something like this:
-<code bash>
-i A apt-xapian-index    -   maintenance and search tools for a Xapian index of Debian packages
-i A exim4               -   metapackage to ease Exim MTA (v4) installation
-i A file                -   Determines file type using "magic" numbers
-i A heirloom-mailx      -   feature-rich BSD mail(1)
-</code>
-To determine why an automatically installed package is present on the system:
-<code bash>
-aptitude why python-debian
-</code>
-Returns something like:
-<code bash>
-i   aptitude         Recommends apt-xapian-index
-i A apt-xapian-index Depends    python-debian (>= 0.1.15)
-</code>
-**NOTE**:  **aptitude search foo** is slower than using **apt-cache search foo** to perform a searc.  The output is also a bit different from **apt-cache**.  Use whichever method is preferred.
